Definition of Degree (Angles)

Degrees are one possible way of measuring angles.

We use the symbol \({}^\circ\) for degrees.

There are \(360^\circ\) in a full rotation.

A straight angle has \(180^\circ\), and a right angle is \(90^\circ\).

We can use a protractor like the one in the picture to measure angles in degrees.
