Reference Angles and Their Calculations

The video tutorial covers the calculation of reference angles and coterminal angles using both degrees and radians. It explains the difference between clockwise and counterclockwise rotations and how these affect angle measurements. The tutorial also provides step-by-step instructions for solving problems from a Kuta Software Algebra 2 worksheet, including handling complex angle scenarios and verifying answers.
