Please help me prove this

Answer 1

use the formula of pythagoras theorem for the triangles,PAQ, RCQ,FPS AND RES

You can use the hint of all the angles of a square is 90°

for the given 4 triangles, PQ, QR, RS AND PS WILL BE THE HYPOTENUSE SIDES.

THUS, being opposite congruent sides you will get quadrilateral PQRS as a parallelogram
