Arrange the following steps in correct order in constructing a square whose one diagonal is 5cm.
Step 1 : Let PQ cut AC at O.
Step 2 : Draw a diagonal AC = 5cm.
Step 3 : Join Ab, BC, CD and DA. Then ABCD is the required square.
Step 4 : Draw PQ the perpendicular bisector of AC.
Step 5 : With O as centre and OA radius draw a circle. Let the circle cut QP at points B and D.
