This month's riddle is an absolute classic (I don't even know its true origins),
so no Internet searching please.
The question is this:
To be considered a solver, either give a proof of impossibility or construct an example tiling.
For completeness, a shape is called convex if for any two points in it, the entire straight line segment between them is also in it. Concave is the opposite. And by "tiling" we mean a partitioning of the area of the polygon.
