Relationship Between Inscribed Angle and Intercepted Arc
Step 1: Drag B and see how the measure of angle DCB and the measure of arc DB change.
Step 2: How are the measures of the inscribed angle and the intercepted arc related?
Step 3: Uncheck the measure of the arc, change the measure of angle DCB.
Step 4: Calculate the measure of the arc, then check the measure of the arc box to see if you are correct.
Step 5: Repeat steps 3 and 4 at least 3 times.
Step 6: Uncheck the measure of the angle box.
Step 7: Change the size of the measure of the arc and calculate the inscribed angle.
Step 8: Check the box to check your answer.
Step 9: Repeat steps 6-8 at least three times.
The measure of the inscribed angle is ______________ the measure of the intercepted arc.
