Lesson Transcript
Instructor: Karin Gonzalez

Karin has taught middle and high school Health and has a master's degree in social work.

In this lesson, you will learn the definition of congruent segments. You will be given examples of congruent segments to further your understanding of the material. Following this lesson will be a brief quiz to test your new knowledge on this subject.

## What are Congruent Segments?

Line segments are different from lines because they have two defined endpoints. Lines, on the other hand, extend out to infinity.

To enrich your vocabulary even further, a ray is a mix between a line and a line segment. It extends to infinity in one direction and has an endpoint on the other end.

Congruent segments are simply line segments that are equal in length. Congruent means equal. Congruent line segments are usually indicated by drawing the same amount of little tic lines in the middle of the segments, perpendicular to the segments. Congruent segments do not need to be parallel to each other; they do not need to be perpendicular, either. In fact, they can be angled in relation to each other in different ways. The important part is that they are equal, or congruent.

## Indicating Congruent Segments in Writing

We indicate a line segment by drawing a line over its two end points.

We indicate that two line segments are congruent by using the congruence symbol.
