Inscribed Angle Exploration
Answer the following questions:
1. What does the measure of the central angle POA tell you about the measure of minor arc PA?
2. Using the angle measure tool, Measure angle PTA, which called an Inscribed Angle of a circle. You can say that the arc PA is "intercepted" by the inscribed angle PTA (just as it is intercepted by the central angle POA as well.
3. What do you see is the relationship between the measure of the arc (from #1) and the measure of the inscribed angle PTA?
