WebAs stated, a central angle in geometry is one whose vertex forms at the center of the circle, with two radii forming its arms that intersect the circle at two different points. Joining these two points will yield an arc on the circle. So, we can also say that a central angle is the angle where an arc subtends at the center of a circle. There is ...
