# From Here to There - Applications of the Distance Formula

Recommended for High School.

## Introduction

Many problems in applied mathematics involve finding the distance between points. If we know the coordinates of a pair of points (*x*_{1}, *y*_{1}) and (*x*_{2}, *y*_{2}), it is easy to find the distance between them by using the distance formula, which is a restatement of the Pythagorean Theorem.

In this activity you will use a pair of Motion Detectors. They will record the Cartesian *x*, *y* coordinates of a rod moving in a star-shaped pattern. The data collected by the detectors will be used to test the distance formula.

## Objectives

- Record the
*x*- and*y*-coordinates of a rod moving in a star pattern. - Use the recorded coordinates to calculate the distances moved between the vertices of the star.
- Compare the calculated distances with direct measurement on the star pattern.
