A unit used to measure angles is called what?

Explanation:
Angles are measured using a standard unit in everyday geometry: degrees. A full circle contains 360 degrees, so this unit lets us express how big an angle is relative to a complete turn. For example, a right angle is 90 degrees, a straight angle is 180 degrees, and so on. Other systems exist—radians tie angles to arc length and the circle’s radius, grads use 400 per circle, and a turn is a full rotation of 360 degrees—but degrees are the most common here. That’s why this unit is the correct choice.
