distance formula of a triangle. So if you know the lengths of two sides all you have to do is square the two lengths add the result then take the square root of the sum to get the length of the hypotenuse. Two squared plus nine squared plus nine squared is going to be equal to our hypotenuse square which Im just calling C is going to be equal to C squared which is really the distance.

Two squared that is four plus nine squared is 81. Youll use the following formula to determine the distance d or length of the line segment between the given coordinates. The length of the hypotenuse is the distance between the two points.
The hypotenuse of the triangle is the distance between the two points.
The Distance Formula itself is actually derived from the Pythagorean Theorem which is a2 b2 c2 a2 b2 c2 where c c is the longest side of a right triangle also known as the hypotenuse and. To find AB or BC only simple subtracting is necessary. PQ2 PR2 QR2 x2-x12 y2-y12 PQ. The distance between the points A and B is given by the formula x2 x12 y2y12 x 2 x 1 2 y 2 y 1 2 Here A 1 -3 x1 y1 and B 5 -8 x2 y2.
