No, a dodecahedron doesn't have perpendicular faces
A dodecahedron need not have any parallel lines.
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.
