Sample MAP Geometry EOC Practice Questions

Try these sample questions to review concepts for the MAP Geometry EOC exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Point P is located at (3, -4). What are the coordinates of P' after a reflection across the x-axis?
A.(3, 4)
B.(-3, -4)
C.(-3, 4)
D.(4, -3)
Explanation: Reflecting a point (x, y) across the x-axis negates the y-coordinate while keeping the x-coordinate unchanged: (x, -y). Thus, (3, -4) becomes (3, 4).
2Triangle ABC has vertex A at (-2, 5). If the triangle is translated by the vector <4, -3>, what are the coordinates of image vertex A'?
A.(-6, 8)
B.(2, 2)
C.(2, 8)
D.(-6, 2)
Explanation: Adding the translation vector <4, -3> to point A(-2, 5) gives A'(-2 + 4, 5 - 3) = (2, 2).
3Point Q(-1, 4) is rotated 90° counterclockwise about the origin. What are the coordinates of Q'?
A.(4, 1)
B.(-1, -4)
C.(1, 4)
D.(-4, -1)
Explanation: Rotating a point (x, y) 90° counterclockwise about the origin transforms it to (-y, x). For Q(-1, 4), the new coordinates are (-4, -1).
4In triangles ABC and DEF, AB = DE, BC = EF, and AC = DF. Which congruence criterion proves that triangle ABC is congruent to triangle DEF?
A.SAS
B.SSS
C.ASA
D.AAS
Explanation: Since all three corresponding sides of the two triangles are equal in length (Side-Side-Side), the triangles are congruent by the SSS Congruence Postulate.
5In isosceles triangle XYZ, XY = XZ. If the vertex angle X measures 40°, what is the measure of base angle Y?
A.40°
B.70°
C.100°
D.140°
Explanation: The sum of angles in a triangle is 180°. In an isosceles triangle, the base angles are equal. So angle Y + angle Z = 180° - 40° = 140°. Since angle Y = angle Z, angle Y = 140° / 2 = 70°.
6A bag contains 5 red marbles and 15 blue marbles. One marble is drawn at random. What is the probability of drawing a red marble?
A.1/3
B.1/5
C.5/15
D.1/4
Explanation: There are 5 red marbles out of 20 total marbles, so P(red) = 5/20 = 1/4.
7The probability of rain tomorrow is 0.35. What is the probability that it does NOT rain tomorrow?
A.0.35
B.0.75
C.1.35
D.0.65
Explanation: The complement rule gives P(no rain) = 1 - P(rain) = 1 - 0.35 = 0.65.
8Two lines intersect forming vertical angles of measures (3x + 15)° and (5x - 25)°. What is the value of x?
A.10
B.30
C.40
D.20
Explanation: Vertical angles are equal. Set 3x + 15 = 5x - 25. Subtract 3x from both sides: 15 = 2x - 25. Add 25: 40 = 2x, so x = 20.
9Triangle PQR is dilated with the center of dilation at the origin to form triangle P'Q'R'. If segment PQ = 6 units and segment P'Q' = 15 units, what is the scale factor of the dilation?
A.2.5
B.0.4
C.9
D.2.25
Explanation: The scale factor k is the ratio of the image length to the original length: k = P'Q' / PQ = 15 / 6 = 2.5.
10Triangles ABC and DEF are similar (ABC ~ DEF). If AB = 8 cm, BC = 12 cm, and DE = 10 cm, what is the length of side EF?
A.15 cm
B.14 cm
C.16 cm
D.20 cm
Explanation: Corresponding sides of similar triangles are proportional: AB/DE = BC/EF. Substituting values: 8/10 = 12/EF, so 8 * EF = 120, EF = 15 cm.

MAP Geometry EOC: Suggested Study Strategy

1Memorize key right triangle trig ratios (sin = opp/hyp, cos = adj/hyp, tan = opp/adj) and exact values for 30-60-90 and 45-45-90 triangles.
2Practice proving triangle congruence (SSS, SAS, ASA, AAS, HL) and using CPCTC in two-column or paragraph proofs.
3Master coordinate geometry formulas: Distance = sqrt((x2-x1)^2 + (y2-y1)^2), Midpoint = ((x1+x2)/2, (y1+y2)/2), and slope criteria for parallel (m1=m2) and perpendicular (m1*m2=-1) lines.
4Review circle angle and arc relationships: inscribed angle = half central angle/intercepted arc, sector area = (theta/360)*pi*r^2, arc length = (theta/360)*2*pi*r.
5Be proficient with volume formulas: Cylinder = pi*r^2*h, Cone = (1/3)*pi*r^2*h, Pyramid = (1/3)*B*h, Sphere = (4/3)*pi*r^3.
