Central angle

This article is a stub. Help us out by expanding it.

A Central angle is just the angle that has its vertex on the center of a circle, and has sides that pass through the circle itself, so as to subtend an arc of the circle between the two points it passes through. The arc the central angle subtends has an angle measure equal to the central angle, and is known as the arc segment's angular distance.
