Parallels and Euclidean Geometry Lines l and m which are coplanar
... Theorem If two coplanar lines are cut by a transversal so that some pair of alternate interior angles are congruent, then the two lines are parallel. // Proposition i.29 is the converse of this theorem, but it is not a theorem of absolute geometry: to prove it, Euclid made use of a new axiom, his l ...
