Theorem cdlemg16

Description: Part of proof of Lemma G of Crawley p. 116; 2nd line p. 117, which says that (our) cdlemg10 "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's law dalaw , in order to make this inference. This final step eliminates the ( RF ) =/= ( RG ) condition from cdlemg12 . TODO: FIX COMMENT. TODO: should we also eliminate P =/= Q here (or earlier)? Do it if we don't need to add it in for something else later. (Contributed by NM, 6-May-2013)
