How to tell if the two vectors are parallel, orthogonal or neither

The video tutorial explains the concepts of vectors, focusing on parallel and perpendicular vectors. It discusses how to determine if vectors are parallel by comparing slopes and explains that perpendicular vectors have a dot product of zero, indicating orthogonality. The tutorial includes a step-by-step calculation of the dot product to demonstrate this concept.
