Pythagorean Theorem Calculator
Find the hypotenuse of a right triangle
About this calculator
The Pythagorean Theorem Calculator helps you find the hypotenuse of a right triangle using the famous formula a² + b² = c². This essential mathematical tool is invaluable for students, engineers, architects, and anyone working with right triangles. Simply input the lengths of the two shorter sides (legs), and instantly calculate the longest side (hypotenuse). Perfect for geometry homework, construction projects, navigation, and real-world applications where precise measurements are crucial.
How to use
Enter the lengths of the two shorter sides of your right triangle into the designated input fields. The calculator will automatically apply the Pythagorean theorem (a² + b² = c²) and display the hypotenuse length. Make sure both leg measurements use the same units for accurate results.
Frequently asked questions
What is the Pythagorean theorem?
The Pythagorean theorem states that in a right triangle, the square of the hypotenuse equals the sum of squares of the other two sides: a² + b² = c².
Can I find a leg length instead of the hypotenuse?
Yes, if you know the hypotenuse and one leg, you can rearrange the formula to find the missing leg: a = √(c² - b²).
What units can I use with this calculator?
You can use any unit of measurement (inches, feet, meters, etc.) as long as both input values use the same unit consistently.
