Investigation of Ratios of Similar Triangles.
Students will use an accompanying worksheet to investigate trig ratios of similar triangles.
What are some things you notice about the ratios above? Explain your thinking.
Why do similar triangles produce the results you’ve obtained above?
Looking at both charts above, describe how Complimentary angles affect their Sine, Cosine, and Tangent values.
Describe, in your own words, why sine, cosine, and tangent have the same ratios for the same angles in similar triangles
