In linear algebra, two vectors are orthogonal if their dot product is zero. The dot product of two vectors is a scalar quantity that measures the similarity between the two vectors. If the dot product is zero, then the two vectors are perpendicular to each other.
There are several ways to determine if two vectors are orthogonal to each other. One way is to use the dot product. If the dot product of two vectors is zero, then the two vectors are orthogonal to each other. Another way to determine if two vectors are orthogonal to each other is to use the cross product. If the cross product of two vectors is zero, then the two vectors are orthogonal to each other.
