The Foundation of Geometry

A² + B² = C². It's the most famous equation in mathematics! Our Pythagorean Theorem Calculator instantly solves for the missing side of any right-angled triangle. Whether you need to find the long hypotenuse or one of the shorter legs, this tool handles the squares and square roots for you. Perfect for students, carpenters ensuring square corners, or physicists calculating vector magnitudes.

Real-World Applications

This theorem isn't just for textbooks. Builders use the "3-4-5" rule (a Pythagorean triple) to ensure walls are perfectly perpendicular. GPS systems use triangulation based on these principles to pinpoint your location. Use this calculator to solve distance problems, check for "square" in construction projects, or simply breeze through your geometry homework.

History Fact: While named after Pythagoras (c. 570 BC), this relationship was known to Babylonian mathematicians 1000 years earlier! They just didn't write down the formal proof.
