Central Angles, Inscribed Angles, and their Intercepted Arcs

Topic:
Angles
This lesson is to be used to discover relationships between central angles, inscribed angles and the measure of the intercepted arc.
Directions: o Check on the checkbox to Show Central Angle and its Measure o Check on the checkbox to Show Arc and its Measure o Drag points C and D and record at least three measures: o Make a conjecture about the relationship between a central angle and its intercepted arc: o Check on the checkbox to HIDE Central Angle and its Measure o Check on the checkbox to Show Inscribed Angle and its Measure o Drag points E, C and D and record at least three measures: o Make a conjecture about the relationship between a central angle and its intercepted arc:
