Square From Diagonal Using Compass and Straight-edge
Given a line segment as the diagonal of a square, construct the square.
Let A-C be the given diagonal.
Step - 1 With A-C as radius and with centers as A & C respectively draw two circles.
Step - 2 Find the points of Intersection of these two circles. Line connecting these is perpendicular bisector of A-C.
Step - 3 with center as center point of A-C draw a circle passing through A & C. Find points of inter-section of this circle with perpendicular bisector of A -C. These are the vertices of square namely B &
Step - 4 Complete the square A-B-C-D and hide all construction lines.
