How Do You Tell If Two Vectors Are Perpendicular? Two vectors are perpendicular when their dot product equals to . displaystyle left< v_1, v_2right>cdotleft< w_1, w_2right>=v_1w_1+v_2w_2. How do you know if two vectors are perpendicular? If two vectors are perpendicular, then their dot-product is equal to zero. The cross-product of two vectors is defined to

Can Three Vectors Be Mutually Perpendicular? Can three vectors be mutually perpendicular? (i.e., the vectors are perpendicular) are said to be orthogonal. In three-space, three vectors can be mutually perpendicular. How do you prove three vectors are perpendicular to each other? choose a first vector v1=(a,b,c) find a second vector orthogonal to v1 that is
