State Euclid's Fifth Postulate: If two lines are drawn which intersect a third in such a way that the sum of the inner angles on the right side is less than two right angles, then the two lines will inevitably intersect each other on that side if extended enough. Prove Euclid's Fifth Postulate proposition is assuming that we accept the Playfair version of the Euclidean Parallel Postulate.
