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.

How to Use Pythagorean Theorem Calculator

This is an all in one Pythagoras theorem calculator, which is used to find any side (a,b), area a or hypotenuse c of a right triangle. It is an easy-to-use tool with a simple interface that requires no effort from your side.

Using the pythagoras calculator online is a two-step procedure i.e. you give inputs by entering values it gives output in the form of results and the step performed during calculations.

The detailed steps given below will help you further to use this calculator online for finding the side lengths of the triangle.

After opening up the pythagorean theorem solver online, first of all, adjust how you want to calculate your results. This tool allows you to receive results according to your requirements.

Solve For

From the drop-down list displaying solve for, select which side of the triangle you need to calculate. You can choose either side a, side b, hypotenuse c or area c according to your mathematical problem.


The next step is to select your desired unit in which you need to receive your results The Pythagoras theorem calculator provides the option to choose the units either as m, cm, mm, yd, ft or in.

Significant Figures

Using this Pythagorean theorem calculator you can also customize the number of significant figures in your answer. Therefore, select the number of sig figs from 3 to 9 available in the drop-down list. Moreover, you can also select the “auto” option for the standard results.


Now it’s time to give inputs of your triangle into this hypotenuse calculator. According to the selected options and given triangle data enter the values in the calculator.

Side a

As the first input, provide the value of the side “a” of the right-angled triangle.

Side b

Similarly, enter the value of the other side (side b) into the calculator.


After rechecking your selected options and entered values now simply click on the calculate. This hypotenuse calculator will provide you with results along with the necessary steps taken to calculate.
