\section{Aspect Frobenius\label{s:tri-aspect-Frobenius}}

The aspect Frobenius is the sum of the edge lengths squared divided by the area
and normalized so that a unit equilateral triangle has a value of $1$.
\[
  q = \frac{{\normvec{{L_0}}}^{2} +
            {\normvec{{L_1}}}^{2} + 
            {\normvec{{L_2}}}^{2}}{4A\sqrt{3}}
\]

Note that in earlier versions of \verd{}, this metric was
called the triangle aspect ratio.
