Triangle Similarity AA
This explores the relationship between two triangles of different sizes with congruent angles
1. What is the relationship between triangle A'BC and triangle D'EF?
2. Select point A and change the size of the triangle, does the relationship remain the same?
3. Select point D and change the size of the triangle, does the relationship remain the same?
Repeat the steps above using different angle measures. Make a conjecture about two triangles with two pairs of congruent corresponding angles.
