Orthogonal

An orthogonal pair of polarized filters put together will block all light, but put a third one between them at a diagonal angle and some light will pass through.

Prove that straight line AB is orthogonal to straight line DC.

These two lines are orthogonal.

A chord and the radius that bisects it are orthogonal.

The normal vector and tangent vector at a given point are orthogonal.

The content of the message should be orthogonal to the means of its delivery.

An orthogonal approach also promotes reuse. If components have specific, well-defined responsibilities, they can be combined with new components in ways that were not envisioned by their original implementors.

Even in a geostate, some people are willing to fight and die for their views, but the institutional change to a polystate seems somewhat orthogonal to such issues.

All of the orthogonals in this painting display an understanding of linear perspective.
