What confuses me about vectors is that a line or line segment has 2 normal vectors each points 90 degrees off the line in question with 180 degrees difference between them. The length or magnitude of the normal vectors aren't needed nearly as much as the actual angle ie which way the normal vector points. It is from that that the reflective angle is compared to incoming angle.
