The routine returns an algebraic representation of the given geometric object.

Users will be asked to provide the names of the axis if they are not assigned to two names and if the second optional argument is not given.

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

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

$\mathrm{point}\left(A\,0\,0\right),\mathrm{point}\left(B\,1\,1\right)\:$

$\mathrm{line}\left(l\,\left[A\,B\right]\right)$

$l$

$\mathrm{Equation}\left(l\,\left[x\,y\right]\right)$

$-x+y=0$
