Web23 Aug 2016 · This fact, surprisingly, cannot be proved from Euclid's axioms; it has to be added as an additional axiom in geometry. This omission of Euclid was first noticed 2000 years after Euclid, by M. Pasch in 1882! Moreover, there are important theorems in Euclid whose complete proof requires Pasch's axiom; without it, the proofs are not valid. Web1. Incidence, Linear Ordering and Pasch’s Axiom (continued) Proof The lines l and m intersect at no more than one point (Proposition 1.1). It follows that the lines l and m cannot intersect at any point other than the point C. The point B lies between A and C, and therefore the point C does not lie between A and B. (Axiom (AFPG-5)).
