orthonormal

Perpendicular vectors, magnitude one

Orthonormal describes a set of vectors that are both orthogonal (perpendicular to each other) and normalized (each having unit length).

The concept is fundamental in linear algebra and physics, where orthonormal bases simplify calculations: The standard basis vectors i, j, and k form an orthonormal set in three-dimensional space.
