triangles to solve problems and to prove relationships in geometric figures. (major)(fluency) form about geometric figures to set up a proportion that accurately models the situation G.SRT.6 Understand that by similarity, side ratios in right triangles are properties of the angles in the triangle, leading to definitions of trigonometric ratios for acute angles. (major) Ability to generalize that side ratios from similar triangles are equal and that these relationships lead to the definition of the six trigonometric ratios When creating lessons that address this standard you may want to also discuss the relationships that exist in Special Right Triangles. G.SRT.7 Explain and use the relationship between the sine and cosine of complementary angles. (major) In this standard, the idea is to use either Sine or Cosine to find the measure of one acute angle and then use the fact that the acute angles in a right triangle are complementary to find the measure of the other acute angle.
