Among the many mathematical formulas whose discovery drastically changed history, the **Pythagorean Theorem** is perhaps the most important. And there are historical records which indicate that knowledge of the Pythagorean Theorem existed even before the Christian era.

To understand the Pythagorean Theorem, you don’t need to have a high skill level in math, since it’s one of the theorems that form the basic foundation on which mathematics is built. So the simplicity of this theorem allows anybody with basic knowledge of mathematics to interpret it and use it to develop much more complex problems.

Answering the question, **“What is the Pythagorean Theorem?”** is fairly simple since the only mathematical formula that this theorem has is the following:

Hypotenuse^2 = LegOne^2 + LegTwo^2

Now, this formula can be used to derive three others that help us find the length of each side of a right triangle; to do this, all we have to do is solve for any of the three sides (hypotenuse or either leg) in order to obtain the exact formula needed to find its length.

Although we may not realize it and often don’t give it the importance it deserves, we can find a great many **applications of the Pythagorean Theorem** in our daily lives. Some examples would be calculating the length of a handicapped access ramp when you know the height and the length from the starting point (where the right angle is found) to where the hypotenuse intersects, or in any other situations in which we need to find the length of the sides of a right triangle, regardless of its size.

As you can see, learning the correct application of the Pythagorean Theorem is essential these days. We hope that you find what you’re looking for on our website and are able to fine tune your knowledge about right triangles.
