How Can We Help?
In geometry, a hexagonal pyramid or hexacone is a pyramid with a hexagonal base upon which are erected six isosceles triangular faces that meet at a point (the apex). Like any pyramid, it is self-dual.
A right hexagonal pyramid with a regular hexagon base has C6v symmetry.
A right regular pyramid is one which has a regular polygon as its base and whose apex is "above" the center of the base, so that the apex, the center of the base and any other vertex form a right triangle.
Vertex coordinates
A hexagonal pyramid of edge length 1 has the following vertices:
These coordinates are a subset of the vertices of the regular triangular tiling.
Representations
STL Hexagonal pyramid
A hexagonal pyramid has the following Coxeter diagrams:
- ox6oo&#x (full symmetry)
- ox3ox&#x (generally a ditrigonal pyramid)
