 # Question: What Is The Length Of A Line Segment Between Two Points?

## What is the length of the segment AB?

We have to measure its length.

The scale is placed along the line-segment putting its zero (0) mark at A.

We see the end B is at the 3 cm mark of the scale.

So the length of the line-segment AB = 3 cm..

## What is the distance between two points?

What is the Distance between Two Points? For any two points there is exactly one line segment connecting them. The distance between two points is the length of the line segment connecting them. Note that the distance between two points is always positive.

## 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 determine the length of a line on a graph?

You can use the Distance Formula to find the length of such a line. This formula is basically the Pythagorean Theorem, which you can see if you imagine the given line segment as the hypotenuse of a right triangle. By using a basic geometric formula, measuring lines on a coordinate path becomes a relatively easy task.

## How did you find the length of each segment?

Find the length of the horizontal and vertical sides by subtracting the x and y values. Then follow the steps for using the Pythagorean theorem to find the length of the unknown side. Remember to use the points on each end of the line segment to find the length of the horizontal and vertical sides.

## How do you find the length of a segment in Khan Academy?

Learn how to find the distance between two points by using the distance formula, which is an application of the Pythagorean theorem. We can rewrite the Pythagorean theorem as d=√((x_2-x_1)²+(y_2-y_1)²) to find the distance between any two points. Created by Sal Khan and CK-12 Foundation.

## How do you calculate time and distance?

You can use the equivalent formula d = rt which means distance equals rate times time. To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time. To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.

## What is the formula for shortest distance?

So, the distance between the circle and the point will be the difference of the distance of the point from the origin and the radius of the circle. Using the Distance Formula , the shortest distance between the point and the circle is |√(x1)2+(y1)2−r | .
