Given lines are parallel:(see fig below)
Angle 2x = 2y(alternate angles)
so x = y So one pair of opposite sides of the quadrilateral formed are parallel.
Similarly z = w <,so other pair of opposite sides of the quadrilateral formed are parallel.
The quadrilateral is a //gm. Now 2x+2z = 180 deg (linear pair) so x +z = 90 deg
The //gm is a rectangle
