Pasch's theorem
WebShort description: Result about 4 points on a line which cannot be derived from Euclid's postulates. In geometry, Pasch's theorem, stated in 1882 by the German mathematician … WebPasch's theorem is a statement about the intersection of a line with a triangle in Euclidean geometry. It states that if a line intersects one side of a triangle, and does not pass through either of the other two vertices, then it must intersect one of the other two sides.

Q.E.D. == $ 2 \Rightarrow 1 $ This one's easy. Assume the plane separation postulate. Given a triangle ABC and a line l intersecting AB, show that l must intersect BC or AC.
WebCrossbar Theorem Theorem 1 Let X be a point interior to BAC. Then the ray −→ AX crosses the segment BC. At Bt C t Xt Proof Let a point D be chosen so that B −A−D. Then we can apply the Pasch axiom to ∆CDB and conclude that ←→ AX crosses either BC or DC. At Web9 Apr 2014 · Pasch stated this axiom in . References [1] M.
