Central Angles and Arcs
https://www.cliffsnotes.com/studyguides/geometry/circles/centralanglesandarcs
Central angles are angles formed by any two radii in a circle. The vertex is the center of the circle. In Figure 1, ∠ AOB is a central angle.. Figure 1 A central angle of a circle.. Arcs. An arc of a circle is a continuous portion of the circle.It consists of two endpoints and all the points on the circle between these endpoints.

Finding a Circle's Center. We can use this idea to find a circle's center: draw a right angle from anywhere on the circle's circumference, then draw the diameter where the two legs hit the circle; do that again but for a different diameter; Where the diameters cross is the center!
