Copy of Circumscribed (Tangent-Tangent) Angles
The vertex is located:
inside the circle
at the center of the circle
outside the circle
on the circle
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.
[math]m\angle CAB=\frac{1}{2}\ast m\angle CHB[/math]
[math]m\angle CAB=2\ast m\angle CHB[/math]
[math]m\angle CAB+m\angle CHB=180[/math]
[math]m\angle CAB=m\angle CHB[/math]
