Special Right Triangles

I teach Special Right Triangles using proportions. My students create 2 notecards: one with a 45-45-90 unit triangle and one with a 30-60-90 triangle. The students never really understand why the 30-60-90 notecard needs two versions. They just know that it works.

With this unit we also do a review of rationalizing denominators.
