How to Calculate Hypotenuse
Calculating the hypotenuse is essential in geometry, construction, and navigation. It helps determine the longest side of a right-angled triangle, enabling accurate measurements in fields like architecture, engineering, and physics. Knowing how to compute it allows you to solve real-world problems involving distances, slopes, and diagonal measurements efficiently.

FAQs
1. Why is hypotenuse calculation important?
Hypotenuse calculation is vital for determining diagonal distances in right-angled triangles. It's used in construction, navigation, and physics to solve spatial problems accurately.
2. What formula calculates hypotenuse?
The Pythagorean theorem: c = √(a² + b²), where 'c' is the hypotenuse, and 'a' and 'b' are the other two sides.
3. Can I use this for non-right triangles?
No. The Pythagorean theorem applies only to right-angled triangles. Use the Law of Cosines for other triangles.
4. Do units affect the calculation?
Ensure both sides use the same unit (e.g., meters or inches). The hypotenuse will be in the same unit.
5. How precise is the result?
Results are precise to decimal places based on your inputs. The calculator uses JavaScript's Math.sqrt() function.
6. Can I calculate with decimal numbers?
Yes. Enter decimal values for sides, and the calculator will process them accurately.
7. What if I get an error?
Ensure both fields contain positive numbers. Negative values or empty fields trigger alerts.
8. Is this tool mobile-friendly?
Yes. The responsive design works on all devices.
9. Why hypotenuse is the longest side?
In right triangles, the hypotenuse opposes the 90° angle, making it longer than either leg due to geometric principles.
10. Can I calculate hypotenuse without a calculator?
Yes. Manually square sides, sum them, and find the square root. This tool automates the process.
Hypotenuse Formula
The hypotenuse is calculated using the Pythagorean theorem: c = √(a² + b²), where 'c' is the hypotenuse, and 'a' and 'b' are the other two sides of the right-angled triangle.
