A dodecahedron can have 8 to 20 vertices.
A dodecahedron need not have any triangular faces.
A dodecahedron has 0 parallel faces
There are at least three faces at a vertex of a dodecahedron, and at most eleven.
12 faces
A dodecahedron has 12 sides.
A dodecahedron can have 8 to 20 vertices.
A dodecahedron can have 8 to 20 vertices.
There are many kinds of dodecahedrons so it's difficult to give a straight answer.
a dodecahedron has 20 vertices and 12 faces
A dodecahedron need not have any triangular faces.
A dodecahedron has 0 parallel faces
A dodecahedron has 30 lines of symmetry. This is because each face of a dodecahedron is a regular pentagon, which has 5 lines of symmetry. Therefore, each face contributes 5 lines of symmetry, and since a dodecahedron has 12 faces, the total number of lines of symmetry is 5 x 12 = 30.
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 is a polyhedron with between 18 and 30 faces.
A dodecahedron need not have any parallel lines.
