Using a dot product, find the angle between any two line segments that join the
center of a regular tetrahedron to its vertices. Hint: Think of the
vertices of the tetrahedron as sitting at the vertices of a cube (at coordinates
(0,0,0), (1,1,0), (1,0,1) and (0,1,1)---you may need to build a model and play
with it to see how this works!)
