In triangles ABC and PQR, A = Q and B =R. Which side of PQR should be equal to side AB of ABC so that the two triangles are congruent? Give a reason for your answer.
Given: In triangles ABC and PQR, A = Q andB =R
By the ASA criterion of congruence, side AB = QR for a triangle to be congruent.
If, AB = QR then ABC QRP.
