Quick Answer: What Is Line Segment Class 9?

What is another name for line segment QR?

Line segments are commonly named in two ways: By the endpoints.

In the figure above, the line segment would be called PQ because it links the two points P and Q.

Recall that points are usually labelled with single upper-case (capital) letters..

What is the measure of a line segment?

So, a line segment is a piece or part of a line having two endpoints. Unlike a line, a line segment has a definite length. The length of a line segment can be measured either in metric units such as millimeters, centimeters, or customary units like feet or inches.

What is an example of a segment?

Market segments are known to respond somewhat predictably to a marketing strategy, plan, or promotion. … For example, common characteristics of a market segment include interests, lifestyle, age, gender, etc. Common examples of market segmentation include geographic, demographic, psychographic, and behavioral.

What is called a line segment?

In geometry, a line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line between its endpoints. A closed line segment includes both endpoints, while an open line segment excludes both endpoints; a half-open line segment includes exactly one of the endpoints.

Which is the best definition of line segment ST?

The part of a line that connects two points. It is the shortest distance between the two points. … But a line segment has definite end points.

How do you find a line segment with two points?

To calculate it:Add both “x” coordinates, divide by 2.Add both “y” coordinates, divide by 2.

Is a ray a line?

In geometry, a ray can be defined as a part of a line that has a fixed starting point but no end point. It can extend infinitely in one direction. On its way to infinity, a ray may pass through more than one point. When naming a ray, it is denoted by drawing a small ray on top of the name of the ray.

What is called line?

In geometry, a line can be defined as a straight one- dimensional figure that has no thickness and extends endlessly in both directions. It is often described as the shortest distance between any two points. Here, P and Q are points on the line. Fun Facts.

How do you draw a line segment with a compass?

The steps to draw a line segment of length 5 cm using ruler and compasses are:Step 1: Draw a line of any length. Mark a point A on the line, which is the starting point of the line segment.Step 2: Using a ruler, place the pointer of the compass 5 cm apart from the pencil’s lead.

What is line example?

The definition of a line is a mark connecting two points, something stretched between two things, or two or more people standing in a row. An example of a line is a horizontal mark drawn on a piece of paper. An example of a line is caution tape marking off the scene of an accident. An example of a line is fishing wire.

What is a line and line segment?

Line: A line is a one-dimensional geometrical figure. It is defined as a straight, long, and a continuous path that is represented using the arrowheads at both directions. It extends in both the directions. Line Segment: A line segment is a straight line that passes through the two points.

What is line segment and Rays?

a ray is a line that has one endpoint and on one side it goes on forever. a line goes on forever in both directions. a line segment has two endpoints.

What is an example of a line segment in real life?

Examples of Line Segments In Real Life Real-world examples of line segments are a pencil, a baseball bat, the cord to your cell phone charger, the edge of a table, etc. Think of a real-life quadrilateral, like a chessboard; it is made of four line segments.

What is Lines and its types?

Types of Lines Vertical lines: are straight up and down and perpendicular to horizontal lines. Horizontal lines: are straight up and down and perpendicular to vertical lines. Diagonal lines: are lines that straight in any direction except vertical or horizontal.
