Answer 4

Okay, so do you know how to take two vectors and find a third vector which is orthogonal to both of them?

Answer 5

Imagine that disk is like the plane....

Answer 6

The vector pointing straight up is the normal vector to that disk.

Answer 7

The disk can be made by taking any two vectors (3D vectors) since any two vectors are coplanar

Answer 8

@FutureMathProfessor Follow so far?
