This geometry video tutorial provides a basic review into inscribed polygons and circumscribed polygons with reference to circles. The opposite angles of a quadrilateral inscribed in a circle are supplementary. This video also explains how to solve the walk around problem when a circle is inscribed in a quadrilateral or when a quadrilateral is circumscribed about a circle. The incenter is the center of the circle when a circle is inscribed in a polygon. The circumcenter is the center of the circle when the circle is circumscribed about the polygon. This geometry video tutorial contains plenty of examples and practice problems.
