... Let l, m, and n be distinct lines. If lkm and mkn, then lkn. Proof (by contradiction): Suppose, to the contrary, that l, m, and n are lines with lkm and mkn but l is not parallel to n. By definition, this means that l and n intersect at some point x on both l and n. Now since lkm, x cannot be on m. ...
