This worksheet lets you explore how regular polygons appoximate a
circle. You can set the radius of the circle and the number of
equally spaced points around the circle used for a regular polygon.
Check boxes let you show or hide the circle, the regular
polygon, and the triangle defined by the center of the circle and the
first edge of the polygon.
