Counter Examples of Congruent Triangles

Author:
Kawa Chan, Eric Smith
Topic:
Congruence, Triangles
Let's see how many different (non-congruent) triangles that we can create given certain circumstances. Move the red dots around to try create different triangles. You can also change the shape of the original triangle, so try changing it's shape. A green triangle represents congruent triangles and orange triangles represent non-congruent triangles.
