# Pythagorean Theorem calculator

The Pythagorean theorem calculator will help you solve Pythagorean problems with ease. Note that the triangle below is only a representation of a triangle.

Your triangle may have a different shape or a different size, but it has to be a right triangle. a =

b =

c =

Guidelines to follow when using the Pythagorean calculator:

• If you are looking for c or the hypotenuse, just enter a and b.
• If you are looking for a, enter b and c and if you are looking for b, enter a and c.
• If you looking for either a or b, make sure that the value you enter for a or b is not bigger or equal to c. Since c is the longest side, it has to be bigger than a or b.
• If the value entered for c is less than the value entered for a or b, the text box will say "NaN" which means "Not a number"

Enjoy the calculator!

## How to use the Pythagorean theorem calculator to check your answers.

Example #1

Suppose you are looking at a right triangle and the side opposite the right angle is missing. However, the legs measure 11 and 60. First, use the Pythagorean theorem to solve the problem. The side opposite the right angle is the hypotenuse or c.

c2 = a2 + b2

c2 = 112 + 602

c2 = 121 + 3600

c2 = 3721

c is equal to the square root of 3721, so c = 61

Now here is how to check your answer with the Pythagorean theorem calculator.

Enter 11 in the field that says " a = "

Enter 60 in the field that says " b = "

Then, click on the button that says " calculate "

You should get the same answer!

Example #2

Suppose you are looking at a right triangle and the side opposite the right angle is equal to 53 and the length of one leg is 45. Find the length of the other leg. In this problem, c = 53 and a = 45

c2 = a2 + b2

532 = 452 + b2

2809 = 2025 + b2

2809 - 2025 =  b2

784 = b2

b is equal to the square root of 784, so b = 28

Now here is how to check your answer with the Pythagorean theorem calculator.

Enter 53 in the field that says " c = "

Enter 45 in the field that says " a = "

Then, click on the button that says " calculate "

Again, you should get the same answer!
