If are to be congruent, name one additional pair of corresponding parts. What criterion did you use?

From the above given questions, we have:


If triangle ABC and triangle PQR need to be congruent then the other additional pair of corresponding part is:


BC = QR


As, two angles of given triangles are already equal.


Therefore,


By ASA congruence rule, we have:
