These notes are for 30-60-90 special right triangles. I give a little background behind why they are called special right triangles. I give a 3 step process on how to find missing side lengths. I allow you the opportunity to do 1 example, then let your students do some practice. I also include notes on what to do if your students come across a 30-60-90 special right triangle problem with equilateral triangles.
