Distance Between 2 Points. Quick Explanation. When we know the horizontal and vertical distances between two points we can calculate the straight line distance like this: distance = √ a2 + b2. Imagine you know the location of two points (A and B) like here. What is the distance between them?

To find the distance between two points ($$x_1, y_1$$) and ($$x_2, y_2$$), all that you need to do is use the coordinates of these ordered pairs and apply the formula pictured below. The distance formula is $ \text{ Distance } = \sqrt{(x_2 -x_1)^2 + (y_2- y_1)^2} $
Walk through deriving a general formula for the distance between two points. The distance between the points ( x 1, y 1) and ( x 2, y 2) is given by the following formula: ( x 2 − x 1) 2 + ( y 2 − y 1) 2. In this article, we're going to derive this formula!
The distance formula calculates the distance between two points by treating the vertical and horizontal distances as sides of a right triangle, and then finding the length of the line (hypotenuse of a right triangle) using the Pythagorean Theorem.
The Distance Formula is a useful tool for calculating the distance between two points that can be arbitrarily represented as points [latex]A[/latex] [latex]\left( {{x_1},{y_1}} \right)[/latex] and [latex]B[/latex] [latex]\left( {{x_2},{y_2}} \right)[/latex] on the coordinate plane.
Derived from the Pythagorean Theorem, the distance formula is used to find the distance between two points in the plane. The Pythagorean Theorem, [latex]{a}^{2}+{b}^{2}={c}^{2}[/latex], is based on a right triangle where a and b are the lengths of the legs adjacent to the right angle, and c is the length of the hypotenuse.
We can define the distance between two points as the length of the line segment that connects the two given points. Distance between two points on the Cartesian plane can be calculated by finding the length of the line segment that joins the given coordinates.
