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 …

The distance formula comes from the Pythagorean theorem. The horizontal leg has length |x2-x1|, the vertical leg has length |y2-y1|, and the hypotenuse has length equal to the distance between the two …

Oops. Something went wrong. Please try again. Uh oh, it looks like we ran into an error. You need to refresh. If this problem persists, tell us.

Let's practice some geometry problems that can be solved by applying the distance formula.

What is the distance formula? The formula gives the distance between two points (x 1, y 1) and (x 2, y 2) on the coordinate plane: (x 2 x 1) 2 + (y 2 y 1) 2

Let's practice some advanced problems on distance formula. We can use Distance formula not just to find the distance but also to find any unknown, if we have the distance. Practice and find out how.

Review and understand the distance formula to calculate the distance between two points on a coordinate plane.

Gee, let me use the distance formula with some variables. But you're going to see, it's actually one of the simplest things you'll learn in algebra and geometry.
