Circles Revisited.
Burke, Maurice
Mathematics Teacher, v85 n7 p573-77 Oct 1992
Discusses six examples that discover supplementary geometry theorems by using three elementary theorems about the relationships between angles and intercepted arcs in circles. Topics in the examples include angles formed by parallel lines and the sum of the interior angles of triangles, convex quadrilaterals, star polygons, and hexagons. (MDH)
