In this activity, students will prove the Pythagorean theorem. This activity is based on the statement that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. Students will have to cut out the shapes in the squares of the two sides and rearrange them to fit into the square of the hypotenuse, thus proving the theorem. Answer Key Included! There is more than one way to solve this, as I discovered when I tested it out with my students. The a
