9. Construct a Square

Square is a polygon contains four equal sides and corners of 90o. The diagonals of square are perpendicular bisectors of each other.

1.Construct a square of sides 40 mm.

Square can be constructed by using drafter and 45-45 set-square and by using compass.

By using drafter and 45-45 set-square

Refer Fig.9-1

1.Draw a horizontal line PQ of any length.

2.By keeping a side of 45-45 set-square on a horizontal scale of drafter, draw two vertical lines AR and BS of any length by keeping the distance between them 40mm.

3.Draw lines from A and B, inclined at 45o to PQ cutting BS at C and AR at D.

4.Draw a line joining C and D. Thus ABCD is a required square.
