[edit] Trivial proof

One should add the trivial Kelly proof using the minimality of the distance between one point and a line which does not contain it.

Huh? The Kelly proof is in the section "Proof of the Sylvester–Gallai theorem". But I think it's longer than the projective duality one, so I don't know why you call it trivial. —David Eppstein 14:51, 24 April 2007 (UTC)

The picture was the right diagram for the Kelly proof, but the words made no sense; now modified. Also I think I would use the word "gem", not "trivial". Just saying.—Preceding unsigned comment added by 18.250.7.232 (talk) 20:44, March 12, 2008

[edit] Redirect

I don't know if Sylvester's matrix theorem is also by the same Sylvester, but since Sylvester's theorem redirects here, I'm adding a disambiguation link Cai 10:21, 24 April 2007 (UTC)
