A line.
A mathemetical line segment does not exist physically for it only has length and no thickness
True
a line or line-segment
None. A line is a 1-dimensional object and so has no thickness. An atom, no matter how small, has a finite thickness and so cannot be IN a line.
In typesetting, the thickness of a line is called its weight and is measured in points.

The thickness of a fluid is called its viscosity.
A line or a plane.

The Nib
In Math, a line does not have any thickness. It is a mathematical concept.Technically no, since its meant to be a one dimensional object (meaning that it can be technically described by one numerical value). But then, a one dimensional object has zero thickness, therefore it would be invisible due to it infinitely small thickness. So a line by definition has no thickness, but all true lines are invisible.
A point has no length, width, or thickness. A line has infinite length but no width or thickness. A plane has infinite length and width but no thickness.
