Answer 1

in triangles ABD and PQS

AB=PQ (given)

AD=PS (given)

<ADB=<PSQ (each of 90°)

so,

triangle ABD congruent triangle PQS

(SAS criteria)

So, <ABD=<PQS (C P C T)

now, in triangle ABC and triangle PQR

AB=PQ (given)

BC=QR (given)

<ABD=<PQS (proved)

so,

triangle ABC congruent triangle PQR

(SAS criteria)

Hence proved. ..

hope it helps you. ........
