The routine computes the sides of triangle g or square g.

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

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

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

$\mathrm{triangle}\left(\mathrm{ABC}\,\left[\mathrm{point}\left(A\,0\,0\right)\,\mathrm{point}\left(B\,3\,0\right)\,\mathrm{point}\left(C\,0\,4\right)\right]\right)\:$

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

$\left[\sqrt{9}\,\sqrt{25}\,\sqrt{16}\right]$

$\mathrm{point}\left(C\,0\,3\right),\mathrm{point}\left(E\,3\,3\right)\:$

$\mathrm{square}\left(\mathrm{Sq}\,\left[A\,B\,E\,C\right]\right)\:$

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

$\frac{\sqrt{18}\sqrt{2}}{2}$
