Question

What is a Central Angle?

Answer 1

Answer:

A central angle is that angle, which forms when two radii meet at the center of a circle.

We call the point where two lines meet to form an angle as a vertex. A central angle's vertex is always at the center point of a circle.

We can find the central angle from this formula:

(central angle) ÷ 360° = (arc length) ÷ circumference (if the arc length and circumference is given.)

Answer 2

Central angles are subtended by an arc between those two points, and the arc length is the central angle of a circle of radius one. The central angle is also known as the arcs angular distance.
