Conway's Circle Theorem
- Author:

This geometric theorem was discovered by John H. Conway. Begin with any triangle. Extend all three sides into line segments equal in length to the opposite side of the triangle. The six outer endpoints of these line segments all sit on a circle. Moreover, the center of the circle is the center of the incircle for the triangle. In the applet below, you are free to move the vertices of the triangle.
