In this lesson you’ll learn how to use the distance formula to calculate the distance between two points. The distance formula is built from the Pythagorean Theorem, so we’ll start with the Pythagorean Theorem, convert it into the distance formula, and then look at how to use the distance formula directly to find the distance between two points.

Read MoreGiven two points A and B in three-dimensional space, we can calculate the distance between them using the distance formula. It doesn’t matter which point is A and which point is B. The fact that we square the differences inside the square root means that all of our values will be positive, which means we’ll get a positive value for the distance between the points.
