Talk:Desargues' Theorem

By the "reciprocal" of this proof (see note added to edit) we actually mean the converse.

Hence we also need to amend the theorem statement to reflect what is proved.

We could also do with improving the presentation of the converse.

Some sources bundle the converse of Desargues' Theorem in with it, and call it and its converse Desargues' Theorem, while others separate them out carefully, and call its converse the "Dual of Desargues' Theorem".

At some stage this will be documented on meticulously, but for now this note will suffice. --prime mover (talk) 18:40, 8 March 2022 (UTC)
