A hexagonal pyramid has seven vertices, twelve edges, and seven faces. One of its faces is hexagon, a base of the pyramid; six others are triangles. Six of the edges make up the pentagon by connecting its six vertices, and the other six edges are known as the lateral edges of the pyramid, meeting at the seventh vertex called the apex.

The family of a regular polygonal base pyramid: tetrahedron, square pyramid, pentagonal pyramid, and hexagonal pyramid. A right pyramid is a pyramid whose base is circumscribed about a circle and the altitude of the pyramid meets the base at the circle's center; otherwise, it is oblique. [ 12 ]

The hexagonal bipyramid has a plane of symmetry (which is horizontal in the figure to the right) where the bases of the two pyramids are joined. This plane is a regular hexagon. There are also six planes of symmetry crossing through the two apices. These planes are rhombic and lie at 30° angles to each other, perpendicular to the horizontal plane.
The Djoser pyramid in Egypt is known as the oldest in the world at 4,700 years old. A new paper published in Archaeological Prospection calls that record into question with the strong claims of a ...
Top left to bottom right: hexagonal pyramid as the family of prismatoids, truncated tetrahedron as the family of Archimedean solids, triakis icosahedron as the family of Catalan solids, and triaugmented triangular prism as the family of both deltahedrons and Johnson solids. All of these classes are convex polyhedrons.
