Answer Key — Geometry (Grades 9–10) Midterm — Quick Check, Units 4–6
- D — 4:25 Areas compare as the square of the scale factor: (2/5)² = 4/25.
- C — 12 The scale factor is 9/6 = 1.5, so EF = 8 × 1.5 = 12.
- D — Corresponding parts of congruent triangles are congruent Once triangles are proven congruent, all matching parts are congruent.
- D — 24/25 cosine = adjacent/hypotenuse = 24/25.
- A — 15 √(81 + 144) = √225 = 15.
- A — 7√2 In a 45°-45°-90° triangle, hypotenuse = leg × √2.
- B — 25π (90/360) × π(10²) = 25π.
- B — 60π 2πr² + 2πrh = 18π + 42π = 60π.
- D — 55° An inscribed angle is half its intercepted arc.
- C — 120 cubic meters V = (1/3)Bh = (1/3)(36)(10) = 120.
