A2 b2 c2 a2 b2 c2 where. 12 Distance Between Two Points. We then add together the squares of those two distances.
Dont let the subscripts scare you.
C c is the longest. 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. Sal finds the distance between two points with the Pythagorean theorem. That is the exercise will not explicitly state that you need to use the Distance Formula.
