PPT-Inscribed & Circumscribed Polygons

Inscribed amp Circumscribed Polygons Lesson 107 A polygon is inscribed in a circle if all of its vertices lie on the circle Inscribed Circumscribed A polygon is circumscribes about a circle if each of its sides is tangent to the circle. IV. All but two of the propositions in this book are constructions to inscribe or circumscribe figures. . Definition . 1. .
