Question

Why is a line considered infinity long?

Answer 1

A line is not considered infinitely long. A line is usually defined as a straight path of an infinite length, meaning that it is presumed to extend indefinitely in both directions. However, in mathematics and geometry, lines are conceptual entities that have no physical existence. In reality, physical lines are limited by the constraints of the space in which they exist. For example, a line drawn on a piece of paper or a line of ink on a whiteboard has a definite and finite length.
