The routine computes the sides of triangle g, the side of a regular polyhedron, or of an archimedean solid.

In case g is a triangle, the output is a list of three element denoting the three sides of g.

The command with(geom3d,sides) allows the use of the abbreviated form of this command.

$\mathrm{with}\left(\mathrm{geom3d}\right)\:$

$\mathrm{dodecahedron}\left(d\,\mathrm{point}\left(o\,0\,0\,0\right)\,1\right)$

$d$

$\mathrm{sides}\left(d\right)$

$\frac{2\sqrt{3}}{3\left(\frac{1}{2}+\frac{\sqrt{5}}{2}\right)}$
