Degrees are a unit that measures angle. 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.
Advanced mathematics usually switches to the radian angle system as the preferred unit to measure angles. As a result, calculators often offer an option to toggle between radians and degrees. Some programming languages only use radians for the trigonometric functions and so, if the user wants to use degrees, they need to convert degrees to radians.
