Find the hypotenuse or either leg of a right triangle from the other two sides.
For a right triangle, a² + b² = c², where c is the hypotenuse and a and b are the legs.
If the legs are 5 and 12, the hypotenuse is 13.
Enter any two sides to find the third—the hypotenuse or either leg.
No. The Pythagorean theorem applies only to right triangles.
That input is invalid for a right triangle; the hypotenuse must be the longest side.
