Unit Description

A right triangle can be solved using the Pythagorean Theorem if two sides are already given. This unit will explore the concepts of right triangle trigonometry to find missing side lengths and angle measures of right triangles when you are not able to use the Pythagorean Theorem. During this unit you will learn about trig ratios and how to use these to find both side lengths and angle measures.

Unit Objectives

1.  To find the sine, cosine, and tangent ratio of sides from a given angle.
2.  To find the missing side length of a right triangle using the Pythagorean Theorem or a Trigonometry Ratio.
3.  To find the angle measures of a right triangle given two side lengths.
4.  To find the side lengths for 30, 60, 90 degree and 45, 45, 90 degree triangles. 
     Then placing these angles on a coordinate plane.
