Concerning merge edit

I'm not sure why this should be merged into the suggested article. If anything, the theorem should be merged into the definition, not the other way around. Nousernameslefttalk and matrix? 19:27, 3 January 2008 (UTC)Reply

Seeing as I've had no response for several days, I'll remove the merge template. Nousernameslefttalk and matrix? 18:42, 5 January 2008 (UTC)Reply

Doubly perspective? edit

Pappus's hexagon theorem uses the terms "double perspective" and "trebly perspective." What does that mean in reference to this? ᛭ LokiClock (talk) 00:30, 19 April 2010 (UTC)Reply

Point O edit

I am lost in the opening sentence, since the first diagram does not contain a Point O. Errantios (talk) 21:38, 24 December 2022 (UTC)Reply

I added the name of point O (center of perspectivity) in the text. As it is the target of a redirect I added it in boldface. This name is given also (without notation) in the diagram. D.Lazard (talk) 12:06, 25 December 2022 (UTC)Reply
