What is the measure of an angle in degrees and as a fraction of a full turn?

An angle is measured in degrees, which is a unit of angular measurement equal to 1/360 of a full rotation. This means that a full turn is equivalent to 360 degrees. As a fraction of a full turn, an angle can be represented as a numerator over 360, where the numerator is the number of degrees the angle measures. For example, a right angle measures 90 degrees, which can be expressed as 90/360 or 1/4 of a full turn.
