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.)
