Talk:Perspective (geometry)

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. Nousernamesleft^{talk 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. Nousernamesleft^{talk 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]
