Question

1. triangles abc and pqr are congruent. which statement about the triangles is true?

○ ∠a = ∠r
○ ∠c = ∠r
○ cb = pq
○ ab = rq

Explanation:

Step1: Recall congruent - triangle rules

Congruent triangles have corresponding sides and angles equal.

Step2: Analyze each option

For two congruent triangles $\triangle ABC$ and $\triangle PQR$, corresponding sides and angles are equal. If $\triangle ABC\cong\triangle PQR$, then $\angle A=\angle P$, $\angle B = \angle Q$, $\angle C=\angle R$, $AB = PQ$, $BC=QR$, $AC = PR$.

Answer:

If the triangles are congruent, the correct - type of statement would be about corresponding equal sides or angles. But since no specific correct option is fully visible in the provided image (the options seem cut - off), we assume based on congruence rules that if we had a full option stating a correct corresponding - side or corresponding - angle equality, that would be the answer. For example, if an option said $AB = PQ$ (assuming correct correspondence), it would be a valid statement about congruent triangles.
