1. Move point C along the circle to any position in the first quadrant only. [br][br]a. What is the relationship between C and C'? [br][br]b. How are the angles CAB and DAC' related? Write down the angle measures.[br][br]c. What is the measure of angle C'AB?[br][br][br]2. Move point C to a new location (still in first quadrant) and answer the questions (a-c) again.[br][br]3. Repeat step 2 for a new location of Point C.
