If two vectors have the same direction or two vectors are parallel to each other, then the dot product of two vectors is the product of their magnitude. Here, θ = 0 degree. so, cos 0 = 1. Therefore,The dot product of orthogonal vectors is always zero. The Cross product of parallel vectors is always zero. Two or more vectors are collinear if their cross product is zero. The magnitude of a vector is a real non-negative value that represents its magnitude. Solved Examples on Types of Vectors.The dot product of parallel vectors.

In Euclidean …Apr 13, 2017 · $\begingroup$ A lot of people like to think of the dot product as a way of measuring the "parallelness" of vectors and the cross product (when it's defined) as a way of measuring the "perpendicularness" of vectors. With this intuition, perpendicular vectors are NOT AT ALL parallel, so their dot product is zero. $\endgroup$ – Dot Product and Normals to Lines and Planes. where A = (a, b) and X = (x,y). where A = (a, b, c) and X = (x,y, z). (Q - P) = d - d = 0. This means that the vector A is orthogonal to any vector PQ between points P and Q of the plane. This also means that vector OA is orthogonal to the plane, so the line OA is perpendicular to the plane.
