The axioms of descriptive geometry, by A.N. Whitehead.
20 COPLANARITY OF LINES [CH. II Assume that a and b do not intersect. Then it is easy to prove that no two of the lines intersect. It follows that no one of the lines c, b, d can intersect any of the planes ab, ac, ad in which it does not lie. Fig. 1. Fig. 2.
