Line segments are congruent if they have the same length. However, they need not be parallel. They can be at any angle or orientation on the plane. In the figure above, there are two congruent line segments.Note they are laying at different angles.If you drag any of the four endpoints, the other segment will change length to remain congruent with the one you are changing. For line segments, 'congruent' is similar to saying 'equals'.n the figure above, there are two congruent line segments. Note they are laying at different angles.
