Central Angles and Inscribed Angles can be confusing for geometry students. This PowerPoint is meant to be taught after you have introduced inscribed angles. RapidFire can be used as a game or a bell-ringer activity. Simply pull up the slideshow, and have your students determine whether the angle in circle is a central angle or an inscribed angle. The second half of the PowerPoint is the same as the first, but it meant for reviewing how the angle measures and the arc measures are related in both topics.
