In order to draw a square inscribed in a circle, we need to follow these steps:
*A diameter of the circle is drawn.
*A perpendicular bisector of the diameter is drawn using the method described in Perpendicular bisector of a segment. This is also a diameter of the circle.
*The resulting four points on the circle are the vertices of the inscribed square.
Therefore, the answer is:
Construct a perpendicular bisector to line AB
