## Construction of A Square

E.g.: How to construct a square given that one of its sides is 60mm

### Procedure:

1. Draw the given side AB to be 60 mm.
2. With centre A and a convenient radius, draw a semicircle at A. use the semicircle to draw a vertical line at AE
3. With center A and a radius AB, draw an arc to cut the vertical line at D, with center B and with the same radius, draw an arc at C.
