Talk:Edge (geometry)

I changed the definition to "joining two adjacent zero-dimensional vertices" because the diagonal of a cube (or square) is not an edge. Do you agree?

Maybe we could also change/add to the definition to allow for polytopes. Aacehm (talk) 16:18, 14 December 2011 (UTC)

Remove zero-dimensional and one-dimensional?

I think that we can remove the word "zero-dimensional" and possibly "one-dimensional". A vertex is a point, which is zero-dimensional. While an edge is a line segment, the article on line segment does not explicitly mention a line segment as being one-dimensional, which might lead to some confusion.

Yes, they seem redundant. I added some pictures and more text for edges on higher figures... Tom Ruen (talk) 22:46, 14 December 2011 (UTC)

Formatting on mobile of the intro section looks horrible for me

Text is very squeezed to the left side of the images, like two characters per line. On iPhone btw Adam El-Sawaf (talk) 08:08, 24 January 2026 (UTC)

Yes, I got the same problem on my Pixel phone. The image gallery was formatted very badly with one image across but spread to almost the whole width of the screen. I switched to a {{multiple image}} template which looks similar on non-mobile layouts but on my phone fits two images across and doesn't try to sandwich any text beside it. —David Eppstein (talk) 08:19, 24 January 2026 (UTC)

Thanks! It looks great to me now too Adam El-Sawaf (talk) 08:36, 24 January 2026 (UTC)
