Final answer:

The Pythagorean Identity, a² + b² = c², is used to calculate the length of the hypotenuse in a right triangle when the lengths of the two legs are known.

Step-by-step explanation:

The Pythagorean Identity, a² + b² = c², is used to calculate the length of the hypotenuse in a right triangle when the lengths of the two legs are known. It can be rewritten as c = √(a² + b²), where c represents the hypotenuse and a and b represent the lengths of the legs.
