NY Regents Geometry Exam Guide 2026: Format, Blueprint, Scoring, and a Free Study Plan

NY Regents Geometry 2026: The Direct Answer

The 2026 NY Regents Geometry exam is a 35-question, three-hour test that measures the New York State Next Generation Mathematics Learning Standards at the Geometry level. NYSED's official Regents Examination in Geometry page is the hub for the current exam, and the Geometry Educator Guide (2024, Next Generation) defines the format, blueprint, tools, and scoring rules.

The exam is best understood as a proof-and-modeling test, not just a calculation test. Of the 80 raw credits available, 32 come from constructed-response questions in Parts II, III, and IV, where you must show work and justify steps. The current Educator Guide says the 6-credit response requires a multi-step, extended logical argument and proof. A student who only drills multiple-choice items leaves 40 percent of the raw credits on the table.

Two practical facts shape prep. First, the NYSED released-exams archive publishes every recent Geometry Regents exam PDF, scoring key, rating guide, model response set, and conversion chart, so you can practice on real items and read official model answers. Second, Geometry is not optional if you want the Advanced Regents Diploma: NYSED's diploma requirements (Section 100.5) place Geometry in the standard three-math assessment route alongside Algebra I and Algebra II; approved alternatives or exemptions may apply.

Current Exam Snapshot

Common Core to Next Generation: Which Exam Applies?

Geometry did not have two versions running side by side. NYSED's implementation timeline identifies January 2025 as the last Common Core administration and June 2025 as the first Next Generation administration. NYSED also stated that the format did not change.

The format stayed at four parts, 35 questions, 80 raw credits, and three hours across the transition. The reference sheet did not stay the same: the January 2025 Common Core booklet included conversions and many area, circle, algebra, and volume formulas, while the current Next Generation sheet lists volume formulas for a cylinder, general prism, sphere, cone, and pyramid only. Use June 2025 and later released exams for the closest standards and reference-sheet match. Older Common Core exams remain useful for overlapping skills, not for the current blueprint or provided-formula list.

The Six Geometry Content Domains

The official blueprint gives percentage ranges, not exact item counts. The Geometry Educator Guide lists six content domains:

The two largest domains together account for roughly 56 to 71 percent of the exam. If you only have a few days, spend them on Congruence and Similarity/Right Triangles/Trigonometry, because they dominate the test.

Congruence (G-CO)

This domain covers transformations in the plane, congruence via rigid motions, proving geometric theorems, and geometric constructions. Expect questions about translations, reflections, rotations, and compositions of rigid motions; triangle congruence criteria (SSS, SAS, ASA, AAS, HL); and proofs of vertical angle, alternate interior angle, triangle sum, isosceles triangle, and parallelogram theorems. Constructions appear regularly (perpendicular bisector, angle bisector, parallel line through a point, equilateral triangle, regular hexagon) and the compass-and-straightedge work must be precise.

Similarity, Right Triangles, & Trigonometry (G-SRT)

This is the heaviest single domain. It includes similarity transformations, AA/SAS/SSS similarity, triangle proportionality, the Pythagorean theorem, special right triangles (45-45-90 and 30-60-90), right-triangle trigonometry (sine, cosine, tangent), and applying trigonometry to general triangles via the Law of Sines and Law of Cosines. The current Educator Guide says the 6-credit constructed response requires a multi-step, extended logical argument and proof involving geometric relationships. Do not assume a specific domain combination in advance.

Circles (G-C)

A small but consistent domain. Know circle theorems (chords, arcs, central and inscribed angles, tangent-radius perpendicularity), arc length, and sector area. The equation of a circle in coordinate form also appears here and in G-GPE. Arc-length and sector-area questions reward clean pi handling; leave pi symbolic until the final step unless the question asks for a decimal.

Expressing Geometric Properties with Equations (G-GPE)

This is coordinate geometry. Use coordinates to prove geometric theorems algebraically: distance, midpoint, slope, parallel and perpendicular slopes, partitioning a line segment in a given ratio, and the equation of a circle. A common Part III or Part IV item asks you to prove a quadrilateral is a parallelogram, rectangle, or rhombus using slopes and distances. Show each condition explicitly.

Geometric Measurement & Dimensions (G-GMD)

This assessed domain covers explaining and using volume formulas for prisms, cylinders, pyramids, cones, and spheres, plus relationships between two- and three-dimensional objects such as cross-sections and rotations. The current reference sheet supplies the five volume-formula entries, but it does not provide area, surface-area, circumference, conversion, Pythagorean, or trigonometric formulas. Practice identifying the solid and its dimensions before substituting.

Modeling with Geometry (G-MG)

This domain applies geometry to real situations: density, optimization, design constraints, and using geometric shapes to describe physical objects. Modeling items frequently overlap with other domains, so a single question might combine similarity, volume, and a real-world constraint. The key skill is naming the geometric model the prompt assumes before calculating.

How the Regents Geometry Exam Is Scored

Raw credits (0 to 80) convert to a Regents scale score (0 to 100) through a published conversion chart that is unique to each administration. NYSED's How Are Regents Examinations Scored? page explains that Regents final scores are not raw percentages; the conversion accounts for form difficulty so that a 65 means the same level of performance across administrations.

The January 2026 conversion chart and June 2026 conversion chart illustrate the curve. On the January 2026 chart, a raw score of 35 maps to the passing scale score of 65. On the June 2026 chart, raw 35 maps to 64 and raw 36 maps to 65, so the exact raw score needed to pass varies by form. Always use the conversion chart for the specific administration you are preparing for.

Performance levels are reported alongside the scale score:

A scale score of 65 (Level 3) is the standard passing cut for a Regents Diploma. Students with disabilities may use qualifying safety-net options, and a 60 to 64 may be appeal-eligible only after at least two attempts and when NYSED's course-average and academic-intervention conditions are met. Ask your school counselor which diploma pathway applies. Rescoring constructed-response items after initial rating is not permitted.

Graduation Requirements: Why Geometry Regents Matters

A standard Regents Diploma requires passing one Mathematics Regents exam with a scale score of 65 or higher. Geometry satisfies that single-math requirement, though most students take Algebra I first.

The Regents Diploma with Advanced Designation uses Algebra I, Geometry, and Algebra II at 65 or higher in the standard three-math assessment route; NYSED-approved alternatives and qualifying exemptions may also satisfy assessment requirements. The Advanced Regents Diploma also requires one life-science and one physical-science assessment. Its World Languages route requires two additional credits, for three total, plus the locally developed Checkpoint B exam; qualifying five-unit Arts or CTE sequences can replace that route.

Geometry is therefore part of the Advanced Designation math pathway. How a particular college weighs that designation is an admissions-policy question, not a NYSED exam rule.

Required Tools and the Reference Sheet

NYSED permits and requires specific tools for the Geometry exam:

• Graphing calculator — schools must make one available for each student's exclusive use throughout the exam. Calculators capable of symbolic manipulation or infrared communication are prohibited. NYSED directs schools to clear, reset, or disable the memory of calculators with programming capability when students enter.
• Compass and straightedge (ruler) — schools are responsible for making both available to every student. A protractor is not listed among the required Geometry tools in the current Educator Guide.
• Detachable reference sheet — included in the booklet. The current Next Generation sheet contains volume formulas for a cylinder, general prism, sphere, cone, and pyramid only. It does not contain the former Common Core sheet's conversions or broader formula list.

Follow your school's directions about whether to use school-supplied tools or an approved personal calculator. Do not rely on a third-party checklist that tells every student to bring equipment NYSED assigns the school to supply.

A graphing-calculator habit worth training: use the calculator to check algebra (graph an equation to confirm a circle's center and radius, verify a system's intersection, plot a transformed figure), but do not use it to replace showing work on constructed-response items. Rating guides require sufficient written work and, when the prompt asks, justification.

How to Prepare by Domain

Congruence and proofs

free NY Regents Geometry practice questionsPractice questions with detailed explanations

Similarity and right-triangle trigonometry

Drill SOH-CAH-TOA until it is automatic, then add Law of Sines and Law of Cosines for non-right triangles. Memorize the special right triangle ratios (1:1:root-2 and 1:root-3:2) and the most common angle-sine pairs (30, 45, and 60 degrees). Constructed-response items can combine diagrams with multi-step reasoning, so name the triangle, identify the given sides relative to the angle, and only then substitute. Treat Part IV separately as the extended logical-argument or proof response described in the current guide.

Coordinate geometry

Make a one-page reference of distance, midpoint, slope, parallel slope, perpendicular slope, and the equation of a circle. Practice proving a quadrilateral is a specific type with a valid sufficient test. For a parallelogram, you might show both pairs of opposite sides parallel, both pairs congruent, or one opposite pair both parallel and congruent. Once a parallelogram is established, perpendicular adjacent sides prove a rectangle and congruent adjacent sides prove a rhombus; proving both establishes a square. Show the conditions your chosen test requires.

Circles, volume, and modeling

For circles, know the equation (x minus h) squared plus (y minus k) squared equals r squared, and how to derive center and radius from it. For volume, identify the solid first, then match the reference-sheet formula. For modeling, translate the word problem into a geometric shape before calculating; a cylindrical water tank 10 meters high with a 4-meter diameter is a cylinder, so use V equals pi times r squared times h with r equal to 2 and h equal to 10.

Constructed Response: How to Earn Credit

Parts II, III, and IV account for 32 of 80 raw credits, which is 40 percent of the exam. The NYSED rating guides and model response sets show what scorers look for. A strong constructed response typically includes:

• The formula, theorem, or relationship you are using.
• Substitution with units and labels when applicable.
• The final answer with the units and rounding the question specifies.
• A short justification that connects the math to the claim (for proof items, a statements-and-reasons sequence).

Partial credit exists. A 4-credit question can earn 0, 1, 2, 3, or 4 credits. A 6-credit Part IV question can earn any integer from 0 to 6. Even if you cannot finish a proof, write the given, a correct relevant step, and its justification; the administration-specific rating guide may award partial credit. A blank earns zero.

One trap to avoid: do not write a true statement that does not answer the question. A scorer is looking for the specific evidence the rubric names, not a general geometry fact. Read the prompt twice, underline the verb (prove, find, determine, explain, justify), and answer exactly that.

---

Common NY Regents Geometry Traps

Treating a scale score as a raw percent. A 65 is not 65 percent of the questions correct. The conversion chart for your administration tells you the raw score needed.

Assuming the old reference sheet still applies. The current Next Generation sheet supplies five volume-formula entries only. Learn those entries, but know the other relationships and conversions the current sheet does not provide.

Forgetting constructions. Construction items are worth real credit and reward careful compass work. Practice perpendicular bisectors, angle bisectors, and parallel lines through a point until they are routine.

Stopping the proof early. A proof item requires a conclusion. If the prompt says prove ABCD is a parallelogram, end with therefore ABCD is a parallelogram after the conditions are shown.

Ignoring requested units and labels. Include units and coordinate notation when the prompt or context requires them. The rating guide allows omitted units when the wording permits, so follow the exact question.

Misreading the question. "Determine" usually requires an answer and a justification. "Explain" requires a written reason. "Find" requires a value. Match the verb to the response.

Using a CAS calculator. Symbolic-manipulating calculators are not permitted. Use a standard graphing calculator such as a TI-84.

A Practical Four-Week Study Plan

If you have less than four weeks, use one current released exam as a shortened or untimed diagnostic, then combine Weeks 2 and 3 around the misses. If you have more time, add the August and June 2025 Next Generation exams. Use January 2025 only for overlapping skills: it is the final Common Core form and uses the obsolete broad reference sheet.

A strong weekly rhythm is three content sessions, two constructed-response sessions, and one full timed exam. Keep sessions short and reviewed. The score gain comes from understanding why an item was wrong, not from rushing through more questions.

---

Test-Day Checklist

• Confirm which administration you are sitting for. As of July 29, the remaining 2026 administration is August 19 at 12:30 p.m.; January 21 and June 23 have passed.
• Follow school procedures for the graphing calculator. The school must make an approved calculator available and clear, reset, or disable programmable memory.
• Confirm that the school will supply a compass and straightedge, as NYSED requires; follow local directions if personal tools are allowed.
• Use pen for written work and pencil for graphs and drawings, following the official exam directions.
• Use the detachable reference sheet for its listed volume formulas; it does not supply the legacy sheet's broader formula and conversion list.
• Answer every Part I question; there is no penalty for guessing on multiple-choice.
• For constructed response, show the formula or theorem, substitution, units, and justification whenever the prompt and rating guide require them.
• Keep your answer sheet aligned to the question number; misaligned sheets cost credits.
• Use the conversion chart only after the exam to estimate your scale score; it is not available during testing.

How to Use OpenExamPrep Practice

free NY Regents Geometry practicePractice questions with detailed explanations

After each set, sort misses by cause:

• wrong theorem or formula
• arithmetic or sign error
• missing justification or unit
• misread prompt or wrong verb
• construction not practiced
• coordinate setup wrong
• circle equation misidentified
• ran out of time on Part IV

Then fix the cause. If your misses are mostly proofs, read the model response set on the most recent released exam and rewrite your proofs in the same format. If your misses are mostly trigonometry, drill SOH-CAH-TOA, special right triangles, and Law of Sines/Cosines until the right ratio is automatic. If your misses are coordinate geometry, make a one-page slope/distance/midpoint reference and redo those items until clean.
