Most of us like playing cricket. If you notice a cricket pitch, it has lines drawn at its ends which denote the batting crease. These lines are actually line segments as their length is ______
fixed
The lines of the batting crease are line segments and not lines because a line segment is a fixed portion of a line and this makes it measurable. Line, on the other hand, has no end-points and hence its length is not fixed, which makes it immeasurable. So any straight path that has fixed endpoints is a line segment.
