how to construct a square (using ruler and compass) whose diagonal

is 6.5cm ?

1)Draw a line AC = 6.5 cm

2) Find the midpoint of the line. Let O be the midpoint of the line.Then draw a line XY perpendicular to AC at O.

3)Now taking O as centre and radius equals to OC ,draw a circle intersecting XY at B and D .

4) Join all the four points A,B,C,D to one another.

Thus ABCD is the required square.
