orthogonal
The word orthogonal^{} comes from the Greek orthe and gonia, or “right angle^{}.” It was originally used as synonym of perpendicular^{}. This is where the use of “orthogonal” in orthogonal lines, orthogonal circles^{}, and other geometric terms come from.
In the realm of linear algebra, two vectors are orthogonal when their dot product^{} is zero, which gave rise a generalization^{} of two vectors on some inner product space^{} (not necessarily dot product) being orthogonal when their inner product^{} is zero.
There are also particular definitions on the following entries:
 •

•
orthogonal polynomials
 •
In a more broad sense, it can be said that two objects are orthogonal if they do not “coincide” in some way.
