Given vector a = [a

_{1}, a_{2}, a_{3}] and vector b = [b_{1}, b_{2}, b_{3}], we can say that the two vectors are**orthogonal**if their dot product is equal to zero. The dot product of vector a and vector b, denoted as**a · b**, is given by:**a · b**= a

_{1}* b

_{1}+ a

_{2}* b

_{2}+ a

_{3}* b

_{3}

To find out if two vectors are orthogonal, simply enter their coordinates in the boxes below and then click the “Check orthogonality” button.
