WebJun 29, 2015 · 1 Answer. The vector that joins ( 0, 0, 0) to ( 1, 1, 1) is not the diagonal of a face, but a diagonal of the cube. Note that if A B and A C are the diagonals of two faces that share a common vertex A, then B C is also the diagonal of a face, and this implies that A B C is equilateral. So the angle would be 60.
