Yff Center of Congruence

Let three Isoscelizers, one for each side, be constructed on a Triangle such that the four interior triangles they determine are congruent. Now parallel-displace these Isoscelizers until they concur in a single point. This point is called the Yff center of congruence and has Triangle Center Function

\begin{displaymath}
\alpha=\sec({\textstyle{1\over 2}}A).
\end{displaymath}
