central angle

Circle's hub measurement

A central angle is an angle whose vertex lies at the center of a circle, with its two sides extending as radii to the circumference.

The central angle determines the arc it intercepts—a 90° central angle cuts off a quarter of the circle.

The central angle of each slice of pizza was about 45 degrees.
