In geometry, the perpendicular distance from a point, P, to a line, L, is the distance from P to L, measured along a line which is perpendicular to L and passes through P.
In three dimensions, a perpendicular distance may also be the distance from a point to a plane, measured along the line that passes through the point and is perpendicular to the plane. Also, it can be the distance between two non-coplanar lines, measured along the line that has perpendicular intersections with them both.

Famous quotes containing the word distance:
“I am considered a misanthropist now and then, because I do not socialize with many people. But it’s only my mind that avoids you, my heart is still with you, and seeks the distance so that it can keep on loving you.”
—Franz Grillparzer (1791–1872)
