Exploring the Pythagorean Theorem through Examples

The video tutorial explains the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the two legs is equal to the square of the hypotenuse. The video demonstrates how to apply this theorem to solve for missing sides in right triangles through three examples. The first example solves for a missing leg, the second for the hypotenuse, and the third involves an isosceles right triangle.

What does the Pythagorean theorem state about the relationship between the sides of a right triangle?

• The square of the hypotenuse equals the sum of the squares of the other two sides.

• The square of each leg equals the square of the hypotenuse divided by two.

• The sum of the squares of the hypotenuse equals twice the square of one leg.

• The sum of the lengths of the two legs equals the length of the hypotenuse.
