The Four-Point Affine Plane Show that the model depicted here for four points satisfies the axioms fur an affine plane, consisting of Axiom I-I, the pertinent part of Axiom 1-5 dealing with a single plane, and the Parallel Postulate (a Unique line exists that passes through a given point parallel to-does not intersect-a given line).
