## Comment

the definition is correct but misleading in combination with the image:

A = a, but B != b

i think it is better to use the formula:

(1-t)a+tb


(and change the b!=0 assumption to a!=b) so that a and b correspond to the endpoints of the line segment as expected.

I've changed a and b to ${\displaystyle \mathbf {u} }$ and ${\displaystyle \mathbf {v} }$ to emphasize that they are vectors and added that ${\displaystyle \mathbf {u} }$ and ${\displaystyle \mathbf {u+v} }$ are the end points of ${\displaystyle L}$. This should help reduce the confusion. Paul August 00:28, 8 November 2006 (UTC)

## Confusing picture

In the current version, we have on top of the page a picture that suggests that a line segment is defined to be the conjunction of two vectors. Can anybody make sense of that? Else I propose that the picture is deleted. Bob.v.R (talk) 14:50, 11 October 2012 (UTC)

The intersection of two rays, rather (and not just any two). It's not the definition I'd use, but it works. —Tamfang (talk) 19:35, 11 October 2012 (UTC)

## Definition

Should the definition of a line segment not be restricted to real vector spaces (real affine geometries) or, if a generalization ist intended, to vector spaces over ordered fields ? Ag2gaeh (talk) 15:27, 19 July 2015 (UTC)

## 1-ball redirect

Hi all. Quick question: Why does 1-ball redirect to here? There's no explanation of 1-ball in the article. Devinthepeng (talk) 15:37, 24 May 2016 (UTC)

I've re-targeted the redirect to n-ball. fgnievinski (talk) 17:16, 24 May 2016 (UTC)
