In this study, the properties of convex hexagons that can generate
rotationally symmetric edge-to-edge tilings are discussed. Since the convex
hexagons are equilateral convex parallelohexagons, convex pentagons generated
by bisecting the hexagons can form rotationally symmetric non-edge-to-edge
tilings. In addition, under certain circumstances, tiling-like patterns with an
equilateral convex polygonal hole at the center can be formed using these
convex hexagons or pentagons.Comment: 23 pages, 28 figures. arXiv admin note: text overlap with
