Lesson Plan
Trigonometric ratios (SOH-CAH-TOA)
Goals / Objectives
Define sine, cosine, and tangent as ratios of specific sides in a right triangle
Correctly identify the opposite side, adjacent side, and hypotenuse relative to a specified acute angle
Set up and evaluate sin, cos, and tan from a labeled right triangle diagram
Use similarity to explain why a trigonometric ratio depends only on the angle, and use it to find a ratio in a similar right triangle
Find all three trigonometric ratios when given two sides of a right triangle
Determine a missing ratio when given one trigonometric ratio
Standards
"Solve problems in a variety of contexts using: ... • right triangle trigonometry." "Use similarity to calculate values of sine, cosine, and tangent."
