  In this study, the properties of convex hexagons that can form rotationally
symmetric edge-to-edge tilings are discussed. Because 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.
