d represents Arc CD and e represents Arc AB
1. <COD is an example of an interior angle. Does it have to be formed at the center? Test your conjecture by moving the points on the circle around.
2. What are segments BD and AC examples of?
3. Write a definition of an interior angle in your own words.
4. Make a table of values using "Big Arc", "Little Arc", "Sum=Big+Little", and "Angle Measure"
5. Adjust one of the points on the circles and record the values in the table.
6. Repeat the process four more times.
7. Is there a relationship between the sum of the Big Arc and Little Arc and the Angle measure? What is it?
8. If you were to create a formula using operations and the Big Arc and Little Arc to find the angle measure, what would it be? Test your formula five times using your values from the table.
