Elongated pentagonal pyramid

In geometry, the elongated pentagonal pyramid is one of the Johnson solids (J₉). As the name suggests, it can be constructed by elongating a pentagonal pyramid (J₂) by attaching a pentagonal prism to its base.

A Johnson solid is one of 92 strictly convex polyhedra that have regular faces but are not uniform (that is, they are not Platonic solids, Archimedean solids, prisms or antiprisms). They were named by Norman Johnson, who first listed these polyhedra in 1966.
