Since $\angle OAC$ and $\angle CBA$ together correspond to arcs adding up to half a circle, they adds up to $90$ degrees.Ī theorem says all inscribed angle of the same arc equal each other. So inscribed angles corresponding to half a circle is half of half of $360$ degrees, which is $90$ degrees. For the same arc the inscribed angle is always half the central angle.

The angle with vertex is at $O$ corresponding of one full circle is $360$ degrees (like if you start at the ray $OA$ and swing a full round) whereas the central angle corresponding to half a circle is half of $360$ degrees. One theorem says the arc corresponding to the inscribed angle $\angle OAC$ and $\angle CBA$ are arc $A'C$ and arc $AC$ respectively, and they together form half a circle. I don't know how theorems are named in Evan's book, but all things I call theorem below should exist in his book. One of them is $A$ the other one we can call it $A'$.īelow is one possible diagram it is also possible that $O$ is not inside the triangle $\Delta ABC$, but the relationship between angles I mentioned below still holds.
