Domain - Similarity, Right Triangles, and Trigonometry
Cluster - Apply trigonometry to general triangles.
[PC.G-SRT.D.9] - (+) Derive the formula A = ½ ab sin(C) for the area of a triangle by drawing an auxiliary line from a vertex perpendicular to the opposite side.
[GEO.G-SRT.C.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.
[MII.G-SRT.C.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.
