# What is the name of convex polyhedra with congruent faces of regular polygons?

The definition of platonic solids is the following (see Wikipedia):

In Euclidean geometry, a Platonic solid is a regular, convex polyhedron with congruent faces of regular polygons and the same number of faces meeting at each vertex.

So, I am curious, that what is the name of the class of solids obtained by omitting the regularity and the equality of the degree of vertexes in the definition of platonic solids?

For example the triangular and pentagonal bipyramid are in this class, but they aren't platonic solids.

• Apart from the cube and the dodecahedron, these would be the deltahedra I guess.

• 'Regularity' of platonic solids refers to the fact that all the faces are congruent regular polygons (& also all the vertices lie on a spherical surface). 'Equality of degree of vertices' of platonic solids refers to the fact that all the vertices are identical i.e. identical faces meet at each vertex of the platonic solid.
