Shearer Action 3!

Author:
Tim Brzezinski
Topic:
Geometry, Right Triangles, Square
Creation of this resource was inspired by this tweet from Catriona Shearer. You can move the LARGE WHITE VERTICES of the right triangle anywhere you'd like at any time. Key Questions: 1) What is the measure of the pink angle? 2) How can we formally prove your response to (1) is ALWAYS TRUE (regardless of the location the right triangle's 3 vertices)?
