One of them is the angle in the center theorem. There are several inscribed angle theorems that we'll be learning today. While we're not solely working with central angles anymore, you'll learn that the central angle of a circle will still come into play when we're going through the example problems in this lesson. Inscribed angles are angles that can be anywhere on the circle's circumference. If we're not working with central angles, then what angles in a circle will we be focusing on? We'll be tackling inscribed angles. However, in this lesson, we won't be working with central angles. These are angles that had their vertices at the center of the circle. Previously, when you worked with angles in a triangle, you were mainly working with central angles.
