Degrees are a unit that measures angles. A full rotation in degrees is equal to . By convention, degrees are measured starting from the rightmost edge of the circle with the positive direction corresponding to counter-clockwise rotation.
Shown below are some common angles measured in degrees. These angles are common since they divide a full rotation into equal parts.
While angles are often introduced using the degree angle system, later in math, angles are typically measured using the radian angle system[1]. To convert an angle from degrees to radians, multiply by (pi) radians and divide by [2]. For example, to convert to radians, multiply by .
