Coterminal angles and Reference Angles
In this calculus worksheet, students identify terminal and coterminal angles using the unit circle. They identify coterminal angles between 0and 2pi and between 0 and 360 degrees. There are 34 questions with an answer key.
Curated OER
Reference Angles
Learn how to measure the reference angles in degrees and radians. Students find reference angles that are coterminal with a given angle.
