A dodecahedron has 0 parallel faces
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.
A dodecahedron need not have any parallel lines.
A dodecahedron is a polyhedron with between 18 and 30 faces.
A dodecahedron is a 12 side polyhedron. A regular dodecahedron has regular pentagons (5 sides) for each face.
A dodecahedron has 20 corners/vertices, 30 edges and 12 faces.
