Lines are infinitely extended. Maybe you meant a line segment. Line segments hav...

Line segments have a minimum of an infinite number of points.

I assume they meant two end points (which cannot be the same point) to which the line segment is bound.

That's one of the paradoxes of Euclidean geometry, where a line/line segment is made up of an infinite number of points, but those points have no length or width, and infinity times 0 is still 0, so technically a line should have no length. Clearly, it does not.

Infinity times zero isn't zero, it's undefined.
