These side lengths are based on powers of the "golden section", G=1+√5/2, or the ratio between the diagonal of a regular pentagon and its side, approximately 1.61. A set of polygonal tiles is provided, with each apical angle of each tile being a multiple of 36 degrees, and the side lengths of the tiles having three possible values, which shall be designated as short, medium and long.
The purpose of the present invention is to provide an assembly puzzle based on the geometry of the regular pentagon.
