Description:
Angles within a circle take diverse forms. Central angles, extending from the circle’s center, match the arcs they cover. Inscribed angles, nested within the circle, are half the measure of the arcs they span. Doubling the inscribed angle produces the angle formed at the circle’s center, while halving the intercepted arc creates the angle between a tangent and a chord. These angles serve vital roles in circle geometry, aiding in measurements and spatial relationships.
