A degree, like a radian, is a unit for the measure of an angle. It is denoted by the degree symbol ${}^{\circ }.$ Degrees can be interpreted as the amount of turn in the rotation between the rays of an angle. Therefore, an angle measure can range from $0^{\circ }$ to $360^{\circ }.$ As can be seen, a circle measures $360^{\circ }.$ A protractor is used to measure an angle in terms of degrees.
