Pasch's theorem proof

Web1. Prove the Crossbar theorem: If ray −−→ AD is between rays −→ AB and −→ AC then −−→ AD intersects segment BC. Proof. Suppose the contrary, that BC does not meet ray −−→ … WebThe theorem can be proved algebraically using four copies of a right triangle with sides a a, b, b, and c c arranged inside a square with side c, c, as in the top half of the diagram. The triangles are similar with area {\frac {1} {2}ab} 21ab, while the small square has side b - a b−a and area (b - a)^2 (b−a)2.
