The vertex [math]\angle[/math]CHB is located:
What is the relationship between the central angle ([math]\angle CAB[/math])and the circumscribed angle ([math]\angle CHB[/math])? Move points A, B, and C to test whether the relationship always holds true.
Find the difference between arc CEB and arc CB? How does this number compare to the [math]m\angle CHB[/math]?
it is double the size of the angle
If you let arc CEB be represented by x and arc CB represented by y, what would be a formula you could use to find [math]m\angle CHB[/math]?
[math]\frac{x-y}{2}[/math]
