Talk:Perspective (geometry)

Concerning merge

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?

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

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]
