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 reason for your answer.
उत्तर
We have given, in ΔABC and ΔPQR, ∠A = ∠Q and ∠B = ∠R
Since, AB and QR are included between equal angles.
Hence, the side of ΔPQR is QR which should be equal to side AB of ΔABC, so that the triangles are congruent by the rule ASA.
