About this free right triangle hypotenuse tool
Calculate the hypotenuse of a right triangle from its two perpendicular sides. Calculators answer a defined arithmetic question using the values you supply. Keep units and currencies consistent, choose the correct starting amount and inspect the assumptions before using a result. Estimates do not replace a lender quotation, an official tax rate, a medical assessment or a jurisdiction-specific deadline rule.
A practical example
A concrete example uses first perpendicular side: 3; second perpendicular side: 4. The result is Hypotenuse: 5.
Before you rely on the result
Results use floating-point arithmetic and are rounded to six decimal places. Confirm units and required precision before using the result. Applies only to right triangles.
