Angles in a Circle Keystone Geometry

Angles in a Circle Keystone Geometry. There are four different types of angles in any given circle. The type of angle is determined by the location of the angles vertex. 1. In the Center of the Circle: Central Angle 2. On the Circle: Inscribed Angle 3. In the Circle: Interior Angle

Inscribed Angles

Inscribed Angles. May 13, 2008. What is an inscribed angle?. An inscribed angle is an angle whose vertex is on a circle and whose sides contain chords of the circle. We say that angle 1 above intercepts the arc shown in red. Measure of an inscribed angle.
