Perpendicularity
Perpendicularity Two lines are said to be perpendicular if they form a right angle; in space, such lines need not necessarily intersect. A line l and a plane p are perpendicular if l is perpendicular to every line lying in p. Two planes are perpendicular if they intersect to form a right dihedral angle. Orthogonality is a more general, and sometimes synonymous, concept of perpendicularity. perpendicularity
