What is the relation between an angle created at the center of a circle and the intercepted arc?
1. Find the measure of angle CAB using the angle measure tool. What do you notice about the value of the angle and arc BC? 2. Move one of the points on the circle, C or B, and see if your hypothesis was correct. 3. What can you conclude about the relationship with central angles and their intercepted arcs? 4. What do you think is the measure of the major arc CDB, if the central angle is 70 degrees?
