WebbIn this section, we show how the dot product can be used to define orthogonality, i.e., when two vectors are perpendicular to each other. Definition. Two vectors x, y in R n are orthogonal or perpendicular if x · y = 0. Notation: x ⊥ y means x · y = 0. Since 0 · x = 0 for any vector x, the zero vector is orthogonal to every vector in R n.
