Query: Triangle angle sums related to translation curves in $\SOL$ geometry   After having investigated the geodesic and translation triangles and their
angle sums in $\NIL$ and $\SLR$ geometries we consider the analogous problem in
$\SOL$ space that is one of the eight 3-dimensional Thurston geometries.
  We analyse the interior angle sums of translation triangles in $\SOL$
geometry and prove that it can be larger or equal than $\pi$.
  In our work we will use the projective model of $\SOL$ described by E.
