Objective: I will be able to determine and explain the type of inscribed triangle formed when one side is the diameter of the circle.

1. Triangle CED is inscribed in Circle B, name the side if the triangle that is also the diameter of the circle?
2. Name and find the measure of the arc intercepted by <CED. Explain how you know the measure of the arc.
3. Knowing the measure of the intercepted arc, what is the measure of <CED? Explain how you know.
4. Drag Point E around the circle. How does this change the measure of the intercepted arc? <CED?
5. Classify any inscribed triangle when one side is the diameter by its angles. Explain how you know.
