Trigonometric Reference Angles
Trigonometric Reference Angles
The reference angle is the acute angle formed by the terminal side of the given angle with the horizontal axis. This Demonstration shows some reference angles for applications in elementary trigonometry. Angles are measured in degrees for students first learning about angles in the unit circle.
