This resource has been contributed by Winpossible, and can also be accessed on their website by clicking here - Distance Formula.

This mini-lesson walks you through the basic concepts of the distance formula and explains how the Pythagorean Theorem is used to derive it. You will learn it with the help of some examples, practice questions with solution, and watching video with explanation by the instructor in own handwriting.

The distance between two points can be calculated by drawing a right triangle in the coordinate plane using the two points as the endpoints of the hypotenuse. Then use the Pythagorean Theorem to find the length of the hypotenuse. You can apply the distance formula knowledge, related critical thinking and deduction in everyday practical situations and real life applications. E.g. use a blue print of your school sectioned with coordinates and find out the distance from the classroom to the closest exit of the building in order to determine the quickest exit in case of an emergency.

You’ll also find here briefing about, how to find the distance between any two points whose coordinates are known. If A(*x*_{1}, *y*_{1}) and B(*x*_{2}, *y*_{2}) are two points then the distance between two points is given by the formula:

*d* = *AB* = ? {(*x*_{2} – *x*_{1})^{2} + (*y*_{2} – *y*_{1})^{2}}.

For example, length of the line segment whose coordinates are (3, -2) and (7, 3), is 6.4 units.
