There are at least three faces at a vertex of a dodecahedron, and at most eleven.
A dodecahedron is a polyhedron with 12 faces, each of which is a regular pentagon. In a dodecahedron, the faces are not parallel to each other. The planes of the faces intersect at various angles, giving the dodecahedron its unique shape and properties.

There are many kinds of dodecahedrons so it's difficult to give a straight answer.
Every dodecahedron - not just an average one, has 12 faces. It can have as few as 8 vertices.
A dodecahedron need not have any parallel lines.

If you mean a dodecahedron then it has 12 faces, 30 edges and 20 vertices
a dodecahedron has 20 vertices and 12 faces
A dodecahedron need not have any triangular faces.
