# Quick Answer: How Long Is Segment AB?

## What is the length of the line segment?

The length of this line segment is the distance between its endpoints A and B.

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..

## Which line segment is the longest?

In an ellipse, the longest chord, which is also the longest diameter, is called the major axis, and a segment from the midpoint of the major axis (the ellipse’s center) to either endpoint of the major axis is called a semi-major axis.

## Is Line AB the same as BA?

It may also be called BA. Line BA is the same as line AB. Both pass through the same two points A and B. … In the figure below, a line segment AB has two end points A and B.

## 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.

## How do you represent a line segment?

Line segments are represented by a single overbar with no arrowheads over the letters representing the two endpoints. Consequently, the line segment above may be represented by either: The notations above are read as “Line Segment GH” and “Line Segment HG” respectively.

## What is segment AB?

Line Segment “AB” AB. The line segment between A and B. Line “AB” The infinite line that includes A and B.

## How do you find the true length of a line?

To find the true length of a line you must take a view parallel to the line; in other words, if a line is a parallel to the folding line in one view, it is shown in true length in the adjacent view.

## How do you find the length of a segment given two points?

By the way, what you are actually doing is using the Pythagorean Theorem on an imaginary right triangle with the line joining the two lines being the hypotenuse. The general formula for distance between two points is the following: √x2+y2 x 2 + y 2 , where x and y are the change in x and y between the two points.

## How do you find the length of a line between two points?

The linear distance between the two points is the square root of the sum of the squared values of the x-axis distance and the y-axis distance. To carry on the example: the distance between (3,2) and (7,8) is sqrt (52), or approximately 7.21 units.

## How do you find a line segment between two points?

Midpoint of a Line SegmentAdd both “x” coordinates, divide by 2.Add both “y” coordinates, divide by 2.
