Properties of a Line

i) A line has no end points but contains infinite number of points.

ii) A line has infinite length but no thickness.

In geometry, a line is a one-dimensional figure made up of infinitely many points extending indefinitely in both directions. The concept of line has no width or thickness, representing an idealized "breadthless length". Lines are fundamental elements in geometry as they form the foundation for constructing shapes and defining other geometrical figures.
