I am not sure about these things about vector:
- Is it true to say that a vector n orthogonal to vector n1 and n2 is the cross product of n1 and n2 ?
- Is it true to say that if a line is parallel to a plane, the normal vector of the plane is orthogonal to the parallel vector of the line ?
- Is the acute angle between two planes the angle created by two normal vectors of those planes ?
- Is it true to say that a vector n orthogonal to vector n1 and n2 is the cross product of n1 and n2 ?
