WebSep 17, 2024 · The two sides of a central angle are radii that hit the circle at the opposite ends of an arc—or as mathematicians say, the angle intercepts the arc. The measure of an arc is the same as the degree measure of the central angle that intercepts it. WebMar 28, 2024 · Central angle = 2 x Inscribed angle. Alternative formula: The central angle of a circle can also be determined if the arc length and the radius forming the angle is know, using the following formula: Central angle = Arc length x 360°/2πr.
