Thousands of years ago, a greek mathematician noted a special relationship between the areas of the squares of the sides of a right triangle. Fast forward to the present... and you can still introduce the Pythagorean Theorem the same way it was originally discovered. Students cut out a variety of different sized squares and triangles, then surround each right triangle with three appropriately sized squares. Their task is to find the area of each square and then to analyze the areas to see if they are related. This activity is intended to introduce the concept, but it can also be used to reinforce it. After I began doing this activity, my students had a much deeper (and more visual) understanding of the relationship between the legs and hypotenuse of a triangle. I'd love to hear about your experience using it! Related Product(s): Pythagorean Theorem Worksheet Pack
