Trigonometric Ratios, BJU Press Geometry, 12.1--CCCS Flipped Geometry #73

This lesson introduces Trigonometric ratios. This will be recorded out-of-sequence because I want to make sure that we get to this as a class this year. I'll fill in Chapters 10 and 11 as we have time later. In a right triangle, the ratios of two legs of a triangle are constant given a particular angle measure. The relationships can be described as Sine, Cosine, and Tangents.
