Calculating the hypotenuse of a right triangle is an essential task in mathematics, physics, engineering, and many real-world applications. Whether you are a student solving geometry problems, a professional working with construction measurements, or just someone curious about math, having a reliable tool can save time and prevent mistakes. Our Hypotenuse Calculator provides a simple and accurate way to find the hypotenuse using the sides of a right triangle.

With this tool, you no longer need to manually apply the Pythagoras theorem. Simply input the lengths of the two perpendicular sides, and the calculator instantly provides the hypotenuse. It’s efficient, precise, and user-friendly for people of all skill levels.

What is a Hypotenuse?

The hypotenuse is the longest side of a right triangle, opposite the right angle. In mathematical terms, if a triangle has sides A and B forming the right angle, the hypotenuse C can be calculated using the Pythagoras theorem: C=A2+B2C = \sqrt{A^2 + B^2}C=A2+B2​

Here, A and B are the perpendicular sides, and C is the hypotenuse.

How to Use the Hypotenuse Calculator

Using the Hypotenuse Calculator is extremely straightforward. Follow these steps to find your result in seconds:

1. Enter Side A:
   Input the length of one perpendicular side of the triangle in the designated field. Ensure the value is a positive number.
2. Enter Side B:
   Enter the length of the other perpendicular side. Like Side A, it must be a positive number.
3. Click Calculate:
   Press the Calculate button to instantly compute the hypotenuse. The result will appear below the input fields, rounded to two decimal places.
4. Reset if Needed:
   If you want to perform another calculation, click the Reset button to clear the previous values and results.

This simple interface ensures that anyone, even those without advanced math skills, can quickly determine the hypotenuse.

Example Usage

Let’s see an example to illustrate how easy it is to use the tool:

Scenario:
You have a right triangle with side A = 3 units and side B = 4 units. You want to find the hypotenuse.

Steps:

1. Enter 3 in the Side A field.
2. Enter 4 in the Side B field.
3. Click Calculate.

Result:
The hypotenuse is calculated as 5.00 units.

This matches the classic 3-4-5 triangle example, verifying the accuracy of the calculator.
