Correct answers: 1 question: Amanda and Stephen wrote the following proofs to prove that vertical angles are congruent. Proving triangle PQR is congruent to triangle MQN : From the above diagram, we are given that all three pairs of corresponding sides of triangle PQR and MQN are congruent. This congruent triangles proofs activity includes 16 proofs with and without CPCTC. The simplest picture would be the letter X . Share. Proving Triangles Congruent DRAFT. Inverse angles are congruent. Theorem: In a pair of intersecting lines the vertically opposite angles are equal. Problem 2 – Developing Proofs.
