Question

Construct a square of side 3 cm.

Answer 1

We know that, each angle of a square is right angle (i.e., 90°).

To construct a square of side 3 cm, use the following steps.

1. Draw a line segment AS of length 3 cm.
2. Now, generate an angle of 90° at points A and B of the line segment and plot the parallel lines AX and BY at these points.
3. Cut AD and SC of length 3 cm from AX and BY, respectively.
4. Draw an angle of 90° at any one of the point C or D and join both points by a line segment CD of length 3 cm.

Thus, ABCD is the required square of side, 3 cm.
