A dodecahedron is a generic term which describes a 3-dimensional shape with 12 polygonal faces. There are approx 6.4 million topologically different convex dodecahedra plus concave ones. They can have 8 to 20 vertices and 18 to 30 edges. A hexagonal bipyramid has only 9 diagonals whereas a regular dodecahedron has 170 (I think).
A dodecahedron has 12 sides.
A dodecahedron can have 8 to 20 vertices.

A dodecahedron is a polyhedron with between 8 and 20 vertices.
Every dodecahedron - not just an average one, has 12 faces. It can have as few as 8 vertices.
