Description 



Inscribed Polygon: A polygon is inscribed in a circle if and only if each of its vertices lie on the circle. 
Triangle ABC, quadrilateral DEGF, and pentagon HIJKL are each
inscribed in a circle. Notice for each inscribed polygon, all the vertices lie
on the circle and the polygon lies entirely inside the circle. The circles that
surround the polygons are called circumcircles.
