The video tutorial explains how to use the Pythagorean theorem to find the length of the hypotenuse in a right triangle. It begins by identifying the hypotenuse as the side opposite the 90° angle. The theorem states that the sum of the squares of the two shorter sides equals the square of the hypotenuse. The video demonstrates the calculation process, showing that the hypotenuse is 17, and discusses recognizing perfect squares.
