| Construct square ABCD:

which has side - length 2 cm;

which has side - length 2 cm

Construction:

1) Draw a line segment ‘AB’ of length 2cm.

2) Now, draw a perpendicular line to the line segment ‘AB’ using protractor at ‘B’.

3) Now taking point ‘B’ as centre draw an arc of length ‘2’cm.

4) The arc intersects the line at point, this point is ‘C’.

5) Join points ‘B’ and ‘C’ to form line segment ‘BC’.

6) Now draw a perpendicular to the line segment ‘BC’ using protractor at point ‘C’.

7) Now draw a perpendicular to the line segment ‘AB’ using protractor at point ‘A’.

8) Join points ‘A’, ’D’ to form line segment ‘AD’ and points ‘C’, ’D’ to form line segment ‘CD’.

9) Thus Square ‘ABCD’ is formed.
