Isotoxal figure 2-dimensional tessellation constructed from regular polygons is isotoxal. For instance, the truncated icosahedron (the familiar soccerball) has two types of edges: hexagon-hexagon and hexagon-pentagon, and it is not possible for a symmetry of the solid to move a hexagon-hexagon edge onto a hexagon-pentagon edge. An isotoxal polyhedron has the same dihedral angle for all edges. There are nine convex isotoxal polyhedra formed from the Platonic solids, 8 formed by the Kepler–Poinsot polyhedra, and six more as quasiregular (3 | p q) star polyhedra and their duals. There are at least 5 polygonal tilings of the Euclidean plane that are isotoxal,
Hexagon (comedy show) selected each year. Recent recipients have included Sarah's Circle, the ALS Association, Hospice Caring, and the Wounded Warrior Project. Hexagon is supported by the affiliated Friends of Hexagon. As of 2014, Hexagon had raised over $3.5 million for charity. Hexagon has received recognition for its work in the Washington community. In 1987, President Ronald Reagan presented Hexagon with the President's Volunteer Action Award for service. In 1993, "Washingtonian" magazine selected Hexagon as "Washingtonian of the Year," the first time an organization was named as the award's recipient. In 1994, the Greater Washington Area Chapter of Hadassah honored Hexagon with its
