In geometry, a line that has no beginning and no end is called an undefined or an infinite line. It goes on forever in both directions and has no endpoints. It is represented by a straight line with arrowheads on both ends to indicate its infinite nature. This type of line can be found in various geometric concepts and calculations, such as in Euclidean geometry.
A line that has no beginning and no end is called an infinite line. Unlike a line segment, which has two endpoints, an infinite line extends infinitely in both directions. It continues indefinitely in both directions and has no specific starting or ending point.
