Web“A vector that is perpendicular to the plane or a vector and has a magnitude 1 is called a unit normal vector.” As we stated above, normal vectors are directed at 90° angles. We have already discussed that unit vectors are also perpendicular or directed at 90° to the remaining axes; hence, we can mix these two terms up.
