\usepackage{xypic}Two vectors, $v_1$ and $v_2$, are orthogonal if and only if their inner product $\left<x,y\right>$is 0. In two dimensions, orthogonal vectors are perpendicular (or in $n$ dimensions in the plane defined by the two vectors.)
A set of vectors is orthogonal when, taken pairwise, any two vectors in the set are orthogonal.
