D x2 x12 y2 y12 Where D is the distance between the points. Dx 1-x 2 2 y 1-y 2 2. So P Q x 2 x 1 2 y 2 y 1 2 z 2 z 1 2.
The Distance Formula itself is actually derived from the Pythagorean Theorem which is a2 b2 c2 where c is the longest side of a right triangle also known as the hypotenuse and a and b are the other shorter sides known as the legs of a right triangle.
On this lesson you will learn how to use the distance formula to find the distance between two points on the coordinate planeFor more MashUp Math content. The distance formula is used to find the distance between any two given points. D sqrt x_2 - x_12 y_2 - y_12 d x2. Using distance formula is much easier than the Pythagorean theorem.
