Source sentences:
text: This is a stronger condition than to say the planes are at right angles; it instead means that the planes have no nonzero vectors in common, and that every vector in one plane is orthogonal to every vector in the other plane.
text: In two dimensions there is only one plane, while in three dimensions all planes have at least one nonzero vector in common, along their line of intersection.
