Introduction
editThe introduction contained the bewildering claim that "in projective geometry, three points determine a line." Obviously, this is not in general true; two points determine a line. Perhaps the writer was thinking that a projective line aX+bY+cZ is determined by three numbers a, b, c. I have removed the offending clause. Wood Thrush (talk) 18:47, 2 January 2017 (UTC)
- Sorry, but I moved your comment and gave it a title to conform to Wikipedia standards. You are quite right to be bewildered by this statement in the lead, and the ones following it are no better. I think you have correctly identified the problem and I will attempt to correct (or remove) the offending passages. --Bill Cherowitzo (talk) 19:43, 2 January 2017 (UTC)
