Question

The sides PQ, PR of triangle PQR are equal, and S,T are points on PR,PQ such that $\angle PSQand\angle PTR$ are right angles.
And hence, the triangles PSR and PSQ are congruent
If the above statement is true then mention answer as 1, else mention 0 if false

Answer 1

In $△PTR$ and $△PSQ$,
$\angle PTR=\angle PSQ$ (Each ${90}^{\circ }$)
$PR=PQ$ (Given)
$\angle TPR=\angle SPQ$ (Common)
Thus, $△PTR\cong △PSQ$ (ASA rule)
