Talk:Prismatic surface

A prismatic surface is a surface generated by all the lines that are parallel to a given line and intersect a broken line that is not in the same plane as the given line.

Sorry, that is bullshit. The 'broken line' should not be in the same plane as 'the given line'?? Two lines ALWAYS share a plane!! — Preceding unsigned comment added by 77.224.184.71 (talk) 23:08, 18 September 2012 (UTC)
