Target Goals:
1. To use the properties of 45°45°90° triangles
2. To use the properties of 30°60°90° triangles
Let’s review some 45-45-90 triangles from yesterday!!
Find the lengths of the indicated sides, leave all answers in simplest radical form!

6.) A square has perimeter 32 inches, how
long is each diagonal?
We have a 2nd types of special right triangle….
30-60-90 Right Triangles
Theorem 8.6
