Remember the perpendicular bisector that we practiced? You can use a perpendicular bisector to inscribe a square inside a circle. Make sure you have your straightedge and compass ready, and work through the slideshow below to inscribe a square in a circle.

Step 1 Start with a circle and a center that is labeled. Then, put one point on the circle and label the point. Step 2 Use a straightedge to draw the diameter. Step 3 Draw a perpendicular bisector of the diameter making sure the bisector intersects the circle as well. Step 4 The four points that are created on the circle are the vertices of the square. Connect them for the final figure.
