Prove, or disprove, Euclid's > parallel postulate, also known as his fifth postulate. It has been known for a long time that it cannot be proved or disproved. If the axiom is asserted, then you have plane geometry. If its inverse is asserted, then you have some kind of curved geometry. For example, it is clearly false in spherical geometry. Accordingly, if neither the axiom, nor is inverse, is asserted, then nothing can be said about parallel lines. Sylvia.
