There is something wrong here, or in my interpretation of thisOriginally Posted by jacs
problem. $\displaystyle \angle CGF$ is right, and $\displaystyle \angle CAF$ cannot be right as $\displaystyle AF$
is a cord and not a tangent to the circle with centre $\displaystyle O$. But opposite

thanks for your help
