Hypotenuse Calculator

If you’ve ever needed to find the hypotenuse of a right triangle, you know it can be tricky without the right formula. Our Hypotenuse Calculator makes this process simple, fast, and accurate. Whether you’re a student, engineer, or DIY enthusiast, this tool saves you time and effort while ensuring precise results.

The hypotenuse is the longest side of a right triangle, opposite the right angle. It can be calculated using the Pythagorean theorem:$$c = \sqrt{a^2 + b^2}$$c=a2+b2​

where a and b are the lengths of the two legs of the triangle, and c is the hypotenuse.

How to Use the Hypotenuse Calculator

1. Input the length of the first leg (a): Enter the value in the first input box.
2. Input the length of the second leg (b): Enter the value in the second input box.
3. Click "Calculate": The calculator will instantly compute the hypotenuse using the Pythagorean theorem.
4. View your result: The hypotenuse (c) will be displayed clearly, ready for use in your calculations.

This tool eliminates manual calculations, reducing the chance of errors and providing instant results.

Example: Using the Hypotenuse Calculator

Suppose you have a right triangle with sides:

• a = 3 units
• b = 4 units

Step 1: Enter 3 in the first box and 4 in the second box.
Step 2: Click “Calculate.”
Step 3: The calculator gives:$$c = \sqrt{3^2 + 4^2} = \sqrt{9 + 16} = \sqrt{25} = 5$$c=32+42​=9+16​=25​=5

So, the hypotenuse is 5 units.

This simple tool works for any numeric input, including decimals, making it versatile for school assignments, home projects, or professional work.
