==Art==

The term "orthogonal line" often has a quite different meaning in the literature of modern art criticism. Many works by painters such as [[Piet Mondrian]] and [[Burgoyne Diller]] are noted for their exclusive use of "orthogonal lines" — not, however, with reference to perspective, but rather referring to lines that are straight and exclusively horizontal or vertical, forming right angles where they intersect.
