# Degrees

Degrees are a unit of measurement for angles, representing the rotation between two rays. The degree angle system divides a full rotation into 360 units called degrees.

In navigation and other areas of applied math, degrees can be further divided into minutes and seconds for more precise measurements. There are 60 minutes in a degree, denoted by the symbol ', and 60 seconds in a minute, denoted by the symbol ".

An angle is a measure of rotation or turning and is usually measured in degrees or radians. In geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex. The size of an angle is determined by the amount of rotation from one ray to the other.

A radian angle is measured by the ratio of the angle's arc length over the radius of a circle. A full rotation in radians is equal to τ (tau) radians.

A circle is a basic shape used throughout mathematics. A circle is defined as a shape where every point along its perimeter is an equal distance from its center.
