Question

from this given statement, select the definition, property, postulate, or theorem that justifies the prove statement. given: △pqr and ∠p≅∠q prove: (overline{pr}congoverline{rq})

Explanation:

The Isosceles - Triangle Theorem states that if two angles of a triangle are congruent, then the sides opposite those angles are congruent. In $\triangle PQR$, since $\angle P\cong\angle Q$, by the Isosceles - Triangle Theorem, $\overline{PR}\cong\overline{RQ}$.

Answer:
