Common Core Math - HS Geometry
Lesson Plan
Understand trigonometric ratios
Goals / Objectives
Explain how similarity of right triangles leads to consistent side ratios for a given acute angle
Define sine, cosine, and tangent ratios for acute angles in right triangles
Calculate trigonometric ratios given the sides of a right triangle
Understand that trigonometric ratios depend only on the angle, not on the size of the triangle
Use the definitions to find side lengths or angle measures in right triangles
Recognize the relationship between trigonometric ratios and the concept of similarity
Standards
HSG.SRT.C.6
HSG.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.
