It is a 3-dimensional simply connected shape with 12 polygonal faces. That is it! It can have as few as 8 or as many as 20 faces, as few as 18 or as many as 30 edges, the faces can all be triangles or the shape can have an endecagonal (11-sided) face. It can have between 9 and 170 diagonals.
It is called an edge: there is no special name.
A polyhedron is a simply connected 3-dimensional simply connected shape which is bounded by polygonal faces. A dodecahedron is a special case of a polyhedron: it is a polyhedron with 12 faces.

A regular dodecahedron does not but it is possible to have a dodecahedron with some triangular faces.
A dodecahedron has 12 faces.
A dodecahedron has pentagonal faces.
A dodecahedron is a polyhedron with 12 faces.A dodecahedron is a three-dimensional shape having twelve plane faces.
A dodecahedron. Do = 2and deca = 10so dodecahedron has 12 faces.
I believe it to be a dodecahedron I believe it to be a dodecahedron +++ You believe correctly: it is a dodecahedron.
