The text says "use the SSS congruence theorem for ' and QPB' to " in order to prove perpendicularity, I'm not sure what needs to be before that first tick. — Preceding unsigned comment added by 71.191.226.78 ( talk) 15:01, 26 December 2011 (UTC)
The lede to this article previously said:
But this is wrong. Any line that intersects a plane is perpendicular to some line in the plane. The correct definition is that a line is perpendicular to a plane if it is perpendicular to every line in the plane. I've changed this definition. — Bkell ( talk) 19:16, 25 August 2013 (UTC)
What is the foot of the perpendicular if it is not at the bottom as in the diagram? I think I know but it could be made explicit. — Preceding unsigned comment added by 86.145.80.46 ( talk) 09:09, 20 July 2017 (UTC)
