Boris, could you provide a short lead? If I do it then I will probably not be allowed to approve it. --[[User:Peter Schmitt|Peter Schmitt]] 23:07, 11 May 2010 (UTC) | Boris, could you provide a short lead? If I do it then I will probably not be allowed to approve it. | ||
Somewhere the long form "straight line" should also be mentioned. | |||

Rather cryptic
"The following demonstrates a line:
Given a line AC Point B is on AC ABC is the same line AC"
— rather cryptic; what could it mean? Boris Tsirelson 19:39, 27 March 2010 (UTC)
Lead
Boris, could you provide a short lead? If I do it then I will probably not be allowed to approve it. Somewhere the long form "straight line" should also be mentioned. --Peter Schmitt 23:07, 11 May 2010 (UTC)
Betweenness
The two conditions assume "three different points", thus the "at least" could be omitted. --Peter Schmitt 23:18, 11 May 2010 (UTC)
Definition via right angles
A link to Pythagorean theorem seems to be appropriate. --Peter Schmitt 23:41, 11 May 2010 (UTC)
