Pyramids with a hexagon or higher base must be composed of isosceles triangles. An alternated hexagon, h{6}, is an equilateral triangle, {3}. A regular hexagon is defined as a hexagon that is both equilateral and equiangular. Prospect Park is shaped roughly like a concave hexagon. Let ABCDEF be a hexagon formed by six tangent lines of a conic section. The building is shaped like an irregular hexagon. A regular skew hexagon is vertex-transitive with equal edge lengths. A truncated hexagon is a dodecagon, t{6}={12}. The same is true of the square of the area of a cyclic hexagon. The 6-vertex edge ring does not conform to the shape of a perfect hexagon. At that stage, the snowflake has the shape of a minute hexagon. The structure is in the form of a hexagon, its angles ornamented with minarets. A truncated hexagon, t{6}, is a dodecagon, {12}, alternating 2 types (colors) of edges. The "regular hexagon" has Dih symmetry, order 12. These symmetries express 9 distinct symmetries of a regular hexagon.
