Angles can be measured in degrees or radians. For the time being, we will strictly talk about angles in terms of their degree measure. The symbol for degrees is Â°. Angles can measure from 0Â° up to 360Â°. Angles with no measure are called zero angles, while angles of 360Â° are full rotations. For our study of geometry, we will primarily focus on three important classifications of angles: acute, obtuse, and right.
