Theorem cdlemg16 36459
Description: Part of proof of Lemma G of [Crawley] p. 116; 2nd line p. 117, which says that (our) cdlemg10 36443 "implies (2)" (of p. 116). No details are provided by the authors, so there may be a shorter proof; but ours requires the 14 lemmas, one using Desargues' law dalaw 35687, in order to make this inference. This final step eliminates the (𝑅𝐹) ≠ (𝑅𝐺) condition from cdlemg12 36452. TODO: FIX COMMENT. TODO: should we also eliminate 𝑃𝑄 here (or earlier)? Do it if we don't need to add it in for something else later. (Contributed by NM, 6-May-2013.)
