GoGeometry Action 106!

Author:
Tim Brzezinski
Topic:
Circle, Triangles
Creation of this applet was inspired by a post from Antonio Gutierrez (GoGeometry). Feel free to move any 1 (or more) the LARGE POINTS at any time. You can adjust the size of the triangle's interior angle with gray vertex by using the gray slider. How can we prove both phenomena dynamically displayed here?
