The degree of an angle is a measurement of the angle, representing of a full rotation.
Degrees are indicated by the degree symbol; one degree would be written .
Degrees are the only units written right after a number, without a space (e.g. , not
)
History
The number 360 as the amount of degrees in a circle was probably adopted because it approximates the number of days in a year.
Another reason could be that ancient astronomers noticed that the stars in the sky seem to advance by approximately of a circle.
