What is a central angle of a circle

The video tutorial explains the basic properties of a circle, focusing on the concept of a central angle. It describes how a circle is defined by a center point and equidistant points forming its boundary. The tutorial introduces angles, vertices, and the specific case of central angles, where the vertex is at the circle's center and the sides are radii. The characteristics of central angles are discussed, emphasizing their geometric properties.

How do the endpoints of an angle relate to the circle?

Explain the significance of the radii in relation to the central angle.
