Line segment what is it

If we know the coordinates of the two endpoints of a line segment, we can calculate the distance between them, and so find the length of the line segment. See Distance between two points coordinate geometry. Home Contact About Subject Index.

Definition: A straight line which links two points without extending beyond them. Try this Adjust the line segment below by dragging an orange dot on an endpoint and see how the segment PQ behaves. After this step, the two points are joined together which shows the line segment of the desired length.

Visit the Methods to Draw a Line Segment page for a detailed explanation. The midpoint of a line segment refers to a point that divides it into two equal parts and is located in the middle of the line segment.

The midpoint of a line segment can be calculated if the coordinates of the endpoints are given. We know that line segments have a fixed length or measure. Thus, the examples of line segments in real life include sides of a polygon, edges of a ruler, edges of a paper, etc.

This bar is considered as the line segment symbol. In order to find the length of a line segment, we use a scale ruler to measure its dimensions.

Two figures are said to be congruent if they are of the same size and shape. Thus, any two line segments can be considered to be congruent if they are of the same length. No, a line segment cannot be extended because it has a fixed and definite length. Although a line can be extended in two opposite directions indefinitely, and a ray can also be extended from one end.

Line Segment Examples Example 1: Identify if the given figure is a line segment, a line, or a ray. Solution: The figure has one starting point but an arrow on the other end. When we draw lines in geometry, we use an arrow at each end to show that it extends infinitely.

A line segment has two endpoints. It contains these endpoints and all the points of the line between them. You can measure the length of a segment, but not of a line. A ray is a part of a line that has one endpoint and goes on infinitely in only one direction.
