Degree & Radian Measure

Objective:

In this page the following goals will be addressed

- How to Convert between Degree and Radians.
- How to graph angles in Standard position.
- How to Determine the Quadrant of the terminal side of angles in standard position.
- How to Find the reference angle of angles graphed in standard position.

What is an Angle?

Definition: An angle is the inclination or turn from one ray (initial) to another ray (terminal) relative to a common point.

What is a Reference Angle?

Definition:The reference angle is the angular seperation between the terminal side and the nearest x axis. The reference angle ranges from 0 to 90 degrees.

What are Coterminal Angles?

Definition: Coterminal angles are angles that have thesame terminal side. Coterminal angles are determined by adding and subtracting 360 degrees
