What is the Pythagorean Theorem?

Back

The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b): a² + b² = c².

What is an example of using the Pythagorean Theorem?

Back

If one side of a right triangle is 3 cm and the other side is 4 cm, the hypotenuse can be found using a² + b² = c²: 3² + 4² = c², so c = 5 cm.
