@Mick I agree the two circles seem like touching each other at only one point, but in fact they aren't.

@Chakra Recall that $B'$ and $B$ are inscribed angles, and hence they have the same measure. The same occurs to $C'$ and $C$. See more information here: en.wikipedia.org/wiki/Inscribed_angle

comment Alternative form of equation of circle?
@AsdrubalBeltran I think you could show your process, since is a different one. It can more comprehensible to OP.

comment Alternative form of equation of circle?
@AsdrubalBeltran It's not necessary that $a=h$ and $b=k$.The coefficients $a$ and $b$ can be $a=nh$ and $b=nk$ where $n$ is a non zero real number.
