→Draw a circle of any radius.
→Draw a line segment AB, called chord of the circle.Produce it from both ends.
→Draw an angle of 90°, with the help of compass at the point where secant cuts the circle at the point A and B.
→The point where these two perpendicular cuts the circle , name it as P and Q.
This is Required Square ABPQ.
To Construct it , we have drawn four line Segments [tex] \Bar{AB},\Bar{AP},\Bar{PQ},\Bar{QB}[/tex].
