What Are Perpendicular Lines? | Best Geometry Review
This video shows how to solve a problem involving perpendicular lines. Given a line l and a point P in the same plane, how many lines through P can be drawn in the plane that are perpendicular to l ? If P is on line l, there can be only one perpendicular line through P. If P is somewhere else, there is still only one line that can be drawn that would be perpendicular to line l.
