## Solution

Dear visitors and friends of Poematics!

Thank you for you answers and solutions.

There were good ideas, but nobody has succeeded to provide a complete solution.

Here is my solution:

To make a flooring of identical regular n-polygons, we need that the interior angle of this polygon be a factor of 360^{0}. Thus n can be 3, 4 or 6, representing respectively regular triangles, squares or hexagons.
