Calculate the missing side of a right triangle using the Pythagorean theorem.
It states that in a right triangle, the square of the hypotenuse equals the sum of the squares of the other two sides: a² + b² = c².
No, the Pythagorean theorem only applies to right triangles. For other triangles, use the law of cosines.
These are sets of three integers that satisfy a² + b² = c², such as (3, 4, 5), (5, 12, 13), and (8, 15, 17).
