Kaden and Maddie need to figure out when the Pythagorean Theorem works. Kaden uses side lengths from an obtuse triangle. Maddie uses lengths from a right triangle.

I have an obtuse triangle with side lengths 3, 4, and 6.

I draw a square with each side the same length as the triangle's side. I count how many little squares it takes to fill each big square.

The Pythagorean Theorem didn't work with this triangle.

3^{2} + 4^{2} ≠ 6^{2}
