1. Lesson 8-3: Trigonometry
Students will use sine, cosine, and tangent ratios to determine side lengths and angle measures in right triangles.
Lesson 8-3: Trigonometry

2. Trigonometric ratios Sine(angle) = opposite/hypotenuse
Cosine(angle) = adjacent/hypotenuse
Tangent(angle) = opposite/adjacent
SOH – CAH – TOA!!!
