The Pythagorean theorem says that the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse. If you know the lengths of all three sides of a triangle, you can use the Pythagorean theorem to verify whether the triangle is a right triangle or not.

It includes exercises for classifying triangles, determining unknown side lengths, and verifying right triangles through the theorem, along with a brief mention of calculating square roots.
