TopNewestHint:As suggested by the problem, the answer is independent of the point (as long as it's contained within).Now, figure out how to prove this fact.

In particular, what can we say about how the circumference is split into these regions?

I don't understand can you help me?

We can consider specific cases and conclude that the answer is 2θ but so far I have not been able to prove it for any general point within the circle. Would 2θ be correct?

Yes, that conjecture is correct.
