WebProof: Consider any line. The three other lines must each have a point in common with the given line (Ax 2). These three points are distinct, otherwise Axiom 3 is violated. Then there are exactly three points on each line. Ax1. There exist exactly 4 lines. Ax2. Any two distinct lines have exactly one point on both of them. Ax3. WebJan 21, 2024 · The proof analysis that leads to the independence of the parallel postulate shows, with the notation a∈l for the incidence of a point a on a line l and par(l, a) for the parallel line construction, the underivability of the sequent b ∈ l, b ∈ p a r (l, a) → a ∈ l: in other words, if point b is incident on line l and on the parallel to ...
