As usual, google is a good place to start:

In the methane molecule, each carbon atom is surrounded by four hydrogen atoms, which form a tetrahedron, with the carbon atom at its center. The bond angle theta is the angle formed by the H-C-H combination. Find the tetrahedron angle theta. Take the C atom to be at (1/2, 1/2, 1/2) and the hydrogen atoms at (1,0,0), (0,1,0), and (0,0,1).
