From Latin: perpendicularis vertical, as a plumb line. A line is perpendicular to another if it meets or crosses it at right angles (90Â°). Try this Drag the orange dot at point A. The line AB will be perpendicular to DF only when it meets it at 90Â°. Perpendicular means at right angles.A line meeting another at a right angle, or 90Â° is said to be perpendicular to it.
