Building up to The Unit Circle

Trig has always been one of my favorite subjects.  We have reviewed right triangle trig and I'm trying to work towards graphing, but first we are going to have to make a stop at the Unit Circle.  

My plan is to develop the side measures of the special right triangles using Pythagorean theorem and right triangle trig before discussing converting degrees to radians.  Below is the very beginning of this lesson.  Stay tuned for the rest.

Btw...I have a super awesome secret door trig foldable for this unit.
