Is there a standard mathematical term for two lines which do not intersect, but whose directions are perpendicular, as in the illustration?

A cube, with three of its edges colored red, green, and blue. The
three edges all go in different directions, but no two share a
vertex.

[ Note: the word is not “skew”, which applies to any two nonparallel nonintersecting lines, whether or not they are perpendicular. ]
