Find opposite face of dodecahedron Can anyone tell which one (A,B,C or D) is the opposite face of the face marked in red in the dodecahedron ? What is the best way to find it? ![dodecahedron](

It is opposite (B); you can find this by marking the faces adjacent to the red face, and then marking the faces adjacent to those; then the remaining face, (B), is opposite the red face.
