Definition #68273 - Preferred

 

definition

x₁ is orthogonal/perpendicular/right/at right angle/rectified/square/normal to x₂, where they (are projected to) intersect orthogonally at locus/on set x₃, otherwise being utterly distinct (and not even on the same axis/scale) in sense x₄

notes

This definition approximately parallels that of panra. For geometric orthogonality, fill x₄ with "geometry". This can be applied to lines, planes, curves, manifolds, vectors (endowed with inner product), etc. x₁ and x₂ are necessarily orthogonal at only x₃ (but may be elsewhere, such as if they are hyperplanes). x₁ and x₂ are symmetric terbri in this word under permutation. Also: "with negative reciprocal slope local to". This is a local property.
