| Fig. 1 The mathematical line: distance between 2 points | 
| If the mathematician says that a line is the distance between two points, we can easily determine whether this definition can be used in Geometry. We remove the two irrelevant points. Is what remains behind a line? | 


| You see, Bill! The line is the distance between my hands. This is the longest distance possible in Geometry because I can't stretch them any further. | 


| So far, all you have is a point, Bill. Now drag it across like this. That's what we call a line |
