GoGeometry Action 103!

Author:
Tim Brzezinski
Topic:
Orthocenter, Triangles
Creation of this applet was inspired by a tweet from Antonio Gutierrez (GoGeometry). You can move the vertices of the triangle anywhere you'd like. You can also control the size of the blue angle by using the blue slider. How can we formally prove what this applet informally illustrates?
