Question

Which congruence criterion do you use in the following cases: a) In triangle ABC and triangle PQR : AB = PQ, BC = QR & CA = RP b) In triangle XYZ and triangle MNO: angle X = angle M, XY = MN & angle Y = angle N ?​

Answer 1

Answer:

In Δ ABC and Δ PQR , AB = PQ, BC = QR; CB and RQ are extended to X and Y respectively. ABX = PQY . Prove that Δ ABC = Δ PQR .
