Question

In triangles $ABC$ and $PQR,\angle A=\angle Q$ and $\angle B=\angle R$. Which side of $\Delta PQR$ should be equal to side $AB$ of $\Delta ABC$ so that the two triangle are congruent? Give reason for your answer.

Answer 1

According to given condition,
For congruency of triangle all sides and angle of one triangle should be equal to other triangle's corresponding parameters.
So, $QR=AB$
