Question

(a) Take a square piece paper name it ABCD.

(b) Fold It in such a way that it’s opposite edges lie on each other this folded line is the

perpendicular bisector of the sides AB and DC .

(c) Take a point G on the folded line now fold the two adjacent vertices B and A of the

square on the perpendicular bisector, such that the folded line pass through other

two vertices C and D of the square.
