We give a two dimensional extension of the three distance theorem. Let $\theta $ be in
${{\mathbf{R}}^{2}}$ and let
$q$ be in
$\mathbf{N}$. There exists a triangulation of
${{\mathbf{R}}^{2}}$ invariant by
${{\mathbf{Z}}^{2}}$-translations, whose set of vertices is
${{\mathbf{Z}}^{2}}\,+\,\{0,\,\theta ,\,\ldots ,\,q\theta \}$, and whose number of different triangles, up to translations, is bounded above by a constant which does not depend on
$\theta $ and
$q$.
