What is the meaning of a line segment and what is the definition of a line segment?

A line segment is a line that has endpoints at both ends and cannot be extended. For example: roads, trains, pencils, books, zebra crossings.

A ray is a straight line formed by the infinite extension of one end of a line segment, and the ray has one and only one end, and the length cannot be measured. For example, infrared.

Flashlights, car headlights.

Shooting lights.

A straight line has no ends, extends indefinitely to both ends, and its length cannot be measured. A straight line is an axisymmetric figure.

There is no such thing as a straight line that extends infinitely in the strict sense of the word. But mathematically on the number line.

It can be seen as a straight line.

The meaning of a line segment is: the size and number of "tangible points" are within a finite range, and are arranged and arranged by a finite number of point diameters and point diameters to form a finite length or distance (straight, curved, and folded).

Most people refer to the positioning of a point where the third degree is zero as a zero point. The zero point belongs to the "invisible point", and the "invisible point" has no point diameter; Any point with a little diameter is a "tangible point".

Because the zero point does not have a point diameter, the line is not composed of zero points and zero points. A line is the sum of the point diameters of the "tangible points" and "tangible points" arranged between the zero and zero points.

A line segment is a finite part (including two endpoints) between two points on a straight line, which is different from a straight line or ray.

A line segment is represented by the letters A, B, or a lowercase letter that represent its two endpoints, and sometimes these letters also indicate the length of the line segment, denoted as line segment AB or line segment BA, and line segment A, where A and B represent the two endpoints of the line segment.

Application of Line Segments:1. The link will be related to the two in different places, and the same is true for other indicative supplements.

2. Separate the two areas in the same place, and other areas such as depth of field and isotope are also the same.

A line segment is defined as a finite portion (including two endpoints) between two points on a line.

Line segment, a general term in technical drawing, refers to one or more different line elements that form a continuous or discontinuous drawing line, such as a line segment of a solid line or a line segment composed of "long dashes, short intervals, points, short intervals, points, and short intervals".

Connect the two points with a ruler to get a line segment. The length of the line segment is the distance between these two points.

A line segment is represented by the letters A, B, or a lowercase letter that denote its two endpoints, and sometimes these letters also indicate the length of the line segment, denoted as line AB or line BA, line A. where a and b represent the two endpoints of the line segment.

The concept of a line segment is to determine a straight line at two points, i.e., a straight line of finite length.

A line segment is simply between two points. Distance. It is wired and cannot be extended. Whereas, rays and straight lines can be extended indefinitely.

A line segment is a segment of a straight line, and two different endpoints are taken on the line, and the line segment is between the endpoints.

Two points on a straight line and the part between them are called line segments, and these two points are called the endpoints of line segments A line segment with a and b as the endpoints can be denoted as line segment AB or line segment BA, and line segment AB and line segment BA represent the same line segment Line segment can be represented by a lowercase letter, such as line segment A

The two points on the line and the part between them are called the segments, and these two points are called the endpoints of the segments.

Features Limited length, can measure two endpoints.

This segment is described.

Segment, a general term in technical drawing, refers to one or more different lines forming a continuous or discontinuous graphic line, such as a line segment of a solid line or a line segment consisting of a double-point dash composed of "long dashes, short intervals, points, short intervals, points, and short intervals". Line segments have the following properties: The line segment between two points is the shortest.

The length of the line segment connecting two points is called the distance between the two points. The two points on the line and the part between them are called the line segments, and these two points are called the endpoints of the line segments. A line segment is represented by a letter or a lowercase letter that represents its two endpoints, and sometimes these letters also indicate the length of the line segment, denoted as line segment AB or line segment BA, line segment A.

where ab represents any two points on a straight line, and the straight line has no distance. The rays also have no distance. Because, a straight line has no endpoint, and a ray has only one endpoint, which can be extended indefinitely.

Two points on a line and the part between them are called segments.

Answer: First, the meaning of the line segment.

A line segment means that there are endpoints at both ends and cannot be extended, which is different from straight lines and rays.

Second, the nature of the line segment.

Of all the lines connecting two points, the line segment is the shortest. Abbreviated as the shortest line segment between two points.

So the sum of the two sides in the triangle is greater than the third side.

Third, the characteristics of the line segment.

1) There is a finite length, which can be measured;

2) There are two endpoints;

3) Symmetry;

4) The line between two points is the shortest distance between two points.

A line segment is a straight line with a start and an end point. Line segments are bounded, finite, have a beginning and an end, and have a certain length.
