Hypotenuse Calculator

Need to find the hypotenuse of a right triangle fast? This free hypotenuse calculator makes it easy. Just enter the lengths of the two shorter sides (the legs), and the tool instantly calculates the hypotenuse using the Pythagorean theorem. Perfect for students, DIY projects, and quick geometry checks.

🧮 What Is a Hypotenuse Calculator?

A hypotenuse calculator helps you find the longest side of a right-angled triangle based on the lengths of the two other sides. It uses the Pythagorean theorem: a² + b² = c², where “c” is the hypotenuse. Instead of solving this manually, the calculator does all the work instantly.

⚙️ How This Calculator Works

This tool simply takes your two inputs (side A and side B), squares them, adds the squares together, and finds the square root of the sum. It supports decimals and whole numbers, making it useful for real-world measurements and classroom exercises alike.

💡 When to Use a Hypotenuse Calculator

Whether you’re a student tackling geometry homework or a builder double-checking measurements, knowing the hypotenuse helps with accuracy and efficiency. This tool is also great for trigonometry studies and design-related projects where precise triangle dimensions are needed.

You don’t need to memorize formulas or do manual math when you use this tool. It’s ideal for quick checks during a test, solving construction layout problems, or verifying triangle dimensions in a design project. The calculator is designed to be accurate and beginner-friendly, with zero distractions and instant answers.

This hypotenuse calculator is useful for learning and teaching geometry concepts. It helps you understand how triangle sides relate and can reinforce your math skills with clear, instant results.
