Geometry
Hypotenuse Calculator
Solve the hypotenuse of a right triangle from the two legs (a² + b² = c²), or solve a missing leg given the hypotenuse and one leg.
Fill in the required fields to see your result.
Geometry
Pythagorean Theorem Calculator
Solve for any side of a right triangle using the Pythagorean theorem, or validate whether three given lengths form a right triangle. Great for construction, navigation, and geometry practice.
