​Angle Measure and Trigonometric Ratios

 
Objective
Measure sides of right triangles with given acute angle measures and calculate approximations of the sin, cos, and tan ratios for the angle measures.

About Geometry Worksheet Assignment 7.13:     

 

Assignment 7.13 is an introduction to the relationship of angle measures and values of trigonometric ratios through using measurement to calculate approximations of the ratios.

 

Prerequisite Skills:  Write trigonometric ratios for right triangles (Assignment 7.12).

 

Theorem:   (The values of trigonometric ratios for any angle measure is constant.)
