We will show the tools which enable
an analytic approach to the

geometry
of space with Cabri 3D. We will show that it is
possible to

better
visually represent space with the help of equations in the

same
screen as the figure. The workshop will focus mainly on planes

and lines
and the algebraic possibilities opened by the equations of

these
objects.
