# Distance between two points (two-space)

## Description

Distance is a numerical description of how far apart objects are. In analytic geometry, the distance between two points of the xy-plane can be found using the distance formula. The formula is easily derived by constructing a right triangle with a leg on the hypotenuse of another (with the other leg orthogonal to the plane that contains the 1st triangle) and applying the Pythagorean theorem.
