"d" is the measure of arc AB.
1. Where is point A located within the circle?
2. What are segments AB and AC examples of?
3. is called a central angle. Looking at this static example, find the measure of <BAC. What is the relationship between the central angle and it's intercepted arc?
4. Move point B around the circle. Does it confirm the conjecture you made in the last question?
5. How would you have to move point B to form a semicircle? What is segment BC called?
