**Student Learning Targets**

- Triangles 4: I can use special triangles to determine geometrically the values of sine, cosine and tangent for angles of 0, 30,45, 60 and 90 without a calculator.

## Opener

- Solve this problem without a calculator. Sketch a 45/45/90 triangle. Give the hypotenuse of this triangle a length of 36. Find the lengths of the legs of this triangle.
- What if the length of the hypotenuse is 35?
