A septahedron is a polyhedron with seven faces. The most common type is the triangular bipyramid, which consists of two triangular pyramids joined at their bases, resulting in seven triangular faces. Other variations of septahedra exist, but they generally have complex geometrical properties. Like other polyhedra, septahedra can be studied in terms of their vertices, edges, and symmetry.

How many edges does a septahedron have?
i think 5 but that is what my Xboyfriend told me i don't now
What 2D shape has at least one line of symmetry and 11 letters and starts with an s?
Septahedron

Is a hexagonal based pyramid also a sextahedron?
No its not. The base still counts as a face, so you'd have seven faces, not six. I believe it would be a septahedron.
