\section{Minimum Angle\label{s:tri-min-angle}}

The minimum included angle of the triangle is
\[
  q =
    \min_{n\in\{0,1,2\}}\left\{\arccos{\left(
      \frac{\vec L_n\cdot\vec L_{n+1}}{\normvec{ L_n}\normvec{ L_{n+1}}}
    \right)}\left(\frac{180\dgr}{\pi}\right)\right\}
\]
measured in degrees.

Note that if any edge vector has zero length, \verd\ will return $q = 360\dgr$.
