Greg drew a pair of parallel lines and a line segment next to each other on a chalkboard.

Which of these statements best compares the pair of parallel lines and the line segment?

 Parallel lines and the line segment have no dimensions of measurement.

 The parallel lines and the line segment always meet at a common endpoint which is called the vertex.

 Parallel lines and a line segment cannot lie on the same plane at the same time because they do not overlap.

 The parallel lines extend infinitely in both directions, and the line segment has two endpoints.
