Theorem dalaw 35842
Description: Desargues's law, derived from Desargues's theorem dath 35692 and with no conditions on the atoms. If triples 𝑃, 𝑄, 𝑅 and 𝑆, 𝑇, 𝑈 are centrally perspective, i.e. ((𝑃 𝑆) (𝑄 𝑇)) (𝑅 𝑈), then they are axially perspective. Theorem 13.3 of [Crawley] p. 110. (Contributed by NM, 7-Oct-2012.)
