Question

1. we can prove that two triangles are similar because their angles are congruent, which theorem is it? a. aa theorem b. asa theorem c. equal sides only d. sss theorem

Explanation:

The question asks for the triangle similarity theorem based on congruent angles. The AA (Angle-Angle) Theorem states that if two angles of one triangle are congruent to two angles of another triangle, the triangles are similar (the third angles are automatically congruent due to triangle angle sum). ASA and SSS are for triangle congruence, not similarity based solely on angles, and "Equal sides only" refers to side conditions, not angles.

Answer:

A. AA Theorem
