**1. Intro to Trigonometry Terms**

**The first video is an introduction to the terms we will be using in the unit and how they connect to the triangle!**

**2. How to Use SOHCAHTOA**

**Find the measurement of angle by determining ratios of the side-lengths of the triangle. This is a great introduction video to calculating sine, cosine and tangent.**

**3. Expanding on Sine, Cosine and Tangent**

**Once you have a handle on using sine, cosine and tangent, take it one step further to use the angle itself to find a missing length of the triangle.**
