Or, oversimplified in a different way:
Method 1: Computer, tell me the angle between these two 3D lines!
Method 2: Computer, look at this (second) 3D line from a few different perspectives (determined by the first line) and then tell me how often it looks more vertical than horizontal. That'll give me a good enough idea of the angle between the two.
