Inscribed Angles

What type of angle is < COB in terms of the activities you've done in this book? What is the relationship between this angle and it's intercepted arc?
Make a table of values using <CAB, <COB, and Arc CB as the columns.
Adjust the point B or C and record the values in each column.
Repeat the last step four more times.
What happens when you move point A? Why do you think this happens?
Is there a formula you could write to predict the value of <CAB given the central angle or intercepted arc measure? If so, what is it?
Test your formula using your table of values.
What if someone wanted to find Arc CB rather than the <CAB. How would the formula change then?
