Investigating Triangle Similarity Theorems
In previous classes, to prove that two triangles are congruent you needed to prove that the triangles had 3 sets of corresponding congruent angles AND 3 sets of corresponding proportional sides.
This activity will help you to discover the "shortcuts" to proving two triangles are similar.
