Understanding the Pythagorean Theorem

Subject Area

Mathematics

Grade(s)

8

Overview

In this video, learn how to use the Pythagorean Theorem to find the distance between two points on a coordinate grid. In the accompanying classroom activity, students apply what they learned in the video as they solve similar problems and discuss solution strategies. To get the most from this lesson, students should be comfortable using the Pythagorean Theorem to find an unknown side of a right triangle, graphing points on the coordinate plane, and finding the distance between points with the same x- or y- values.
