## Introduction to Pythagorean Theorem Calculator

The pythagorean calculator is a free math calculator that is used to simplify the equations involving the Pythagoras theorem. To use the online Pythagorean tool you simply have to input the values of the two sides of a right-angled triangle and the third side is calculated as a result.

As you know distance formula is an application of pythagorean theorem. You can also use 3d distance calculator to calculate the distance between two points.

## Pythagorean Theorem Calculator

It is an online tool that utilizes the Pythagorean theorem in order to find the length of the third side of a triangle. If the lengths of the other two sides of a right-angled triangle are known then using the pythagorean calculator the third length could be determined with a single click.

You can save your valuable time and receive accurate results with this calculator in no time. All you have to do is enter the values of the first two sides in order to get output.

With this Pythagoras theorem calculator, you can choose whether you want to solve the Pythagorean theorem for Side a, Side b, Hypotenuse c or Area b. Moreover, you can also select your desired unit from the dropdown list and the number of significant figures up to which you want to have your answer.

As Calculatores provides tons of online tools which you can use anytime free. You can calculate average online and calculate remainder online to make your calculations easy.

## What is Pythagorean Theorem

The Pythagoras theorem defines the relationship between all the three sides of a right-angled triangle. According to the Pythagorean theorem, the sum of two squared sides of a triangle is equal to the squared of the hypotenuse, provided that the triangle is a right-angle triangle.

Therefore, according to the Pythagoras theorem, the squared length of the opposite side of the right angle is equal to the sum of the squared lengths of both of the remaining sides. Mathematically, we express this theorem in the equation **a2 + b2 = c2**.

## How to Calculate Pythagorean Theorem

The problems involving the Pythagorean theorem are calculated using the formula a2 + b2 = c2. By placing values into this formula we can find the Pythagorean theorem for the given problem.

**Related:** Calculatores provide many other educational tools that are solving daily problems of people whether they are on work or studying. Such as you can use our online Permutation and combination calculator or cylinder volume calculator in terms of pi for free.

The Pythagorean theorem is also calculated to derive the hypotenuse equation, in which the hypotenuse equals the under-root of the squares of the other two lengths squared.

By arranging the Pythagorean theorem into different ways we can calculate the different sides of a right-angled triangle accordingly. For instance, if we need to calculate the side “a” of the triangle we arrange the equation in the form √(b2 - c2).

Similarly, the Pythagorean theorem is arranged in the form √(a2 - c2) for the side “b”. However, the Pythagoras theorem is calculated in the form √(a2 + b2) for finding the hypotenuse.
