What is meant by the perpendicular distance? I have a question to answer which is something along the lines of: Find the perpendicular distance of point P from line l. Tera_Dragon

It is the shortest distance between two points, the line that goes from that point to the line forms 90° with the line or plane.

But the question says the perpendicular distance of the point from a line.

Think of drawing a line from the point P to the line l such that the line you draw makes a 90 degree angle with line l. You must then find the length of this new line.

I get it now thanks. I was getting confused because I thought that P was on the line l... :S
