Problem Statement
Is it possible to divide the plane into polygons so that each polygon is transformed into itself under some rotation by degrees about some point? All sides of these polygons must be greater than cm.
(A polygon is the part of a plane bounded by one non-self-intersect-ing closed broken line, not necessarily convex.)(A. Andjans, Riga)
