*Learning Goal: Allow students to explore and discover trigonometric ratios and apply discoveries to solve problems.*

# Note

This lesson was inspired by Kate Nowak, Lisa Bejarano, and New Visions.

# Classwork

# Standards:

**Common Core**- 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.
- HSG.SRT.C.8 – Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems.

**TEKS**- G.9(A) – determine the lengths of sides and measures of angles in a right triangle by applying the trigonometric ratios sine, cosine, and tangent to solve problems
