I believe that there is an error in the equation $\psi = \theta + \phi - kA$. From figure [10], the angle sum of the triangle should be $\theta/2 + \phi/2 + (\pi - \psi/2)$. Then $E=kA$ implies $(\theta/2 + \phi/2 + (\pi - \psi/2)) - \pi = kA$ which reduces to $\psi = \theta + \phi - 2kA$.
Please ignore if the error (if it actually turns out to be an error) has already been resolved in later editions.
