The Pythagorean Theorem states that, * in a right triangle, *the two smaller squares made from the triangles legs add up to equal the biggest square made from the hypotenuse.

The lengths of the legs are commonly labeled as **a** and **b** and the hypotenuse length is labeled as **c**.

REMEMBER:

**HYPOTENUSE: c** is the **longest side** of the triangle

**LEGS: a** and **b** are the other two sides

## What is the Pythagorean Theorem?

In short the Pythagorean Theorem can be explain with the formula below.

## a^{2} + b^{2} = c^{2}

AGAIN, THIS IS ONLY TRUE FOR **RIGHT TRIANGLES**!

Here are other examples:
