Question

prove that the bisector of interior angle of a rectangle form a square​

Answer 1

Here angle 1 = 90/2 = 45 also angle 2 = 90/2 = 45 So in triangle AXD, angle AXD = 180−45−45= 90 So angle WXY = 90 degree [vertically opposite angle]

Similarly in triangle BCZ angle CZB = angle WZY = 90 degree

Since all the angles will be 90 degree and hence it will be a square.
