Sample Questions

1multiple correct

Which of the following are conditions for triangle similarity? (Select all correct answers)

Show answer

AA (Angle-Angle), SSS (Side-Side-Side proportional), SAS (Side-Angle-Side proportional)

The three conditions for triangle similarity are: AA (two angles equal), SSS (all three sides proportional), and SAS (two sides proportional with included angle equal). ASA and RHS are congruence conditions, not similarity.

2multiple choice

In a triangle ABC, D and E are points on AB and AC such that DE || BC. If AD = 4 cm, AB = 10 cm, and AC = 15 cm, find AE.

Show answer

6 cm

By Basic Proportionality Theorem, AD/AB = AE/AC → 4/10 = AE/15 → AE = (4 × 15)/10 = 60/10 = 6 cm

3multiple correct

Which of the following statements about similar triangles are true? (Select all correct)

Show answer

Corresponding angles are equal, Corresponding sides are proportional, All congruent triangles are similar

Similar triangles have equal corresponding angles and proportional corresponding sides. All congruent triangles are similar (same shape and size), but not all similar triangles are congruent (they may have different sizes).

4multiple choice

Two triangles have sides in the ratio 3:4. If the area of the smaller triangle is 27 cm², find the area of the larger triangle.

Show answer

48 cm²

Side ratio = 3:4, so area ratio = 3²:4² = 9:16. If smaller area = 27 cm², then larger area = (16/9) × 27 = 16 × 3 = 48 cm²
