What is the formula for the Pythagorean theorem?

A² + B² = C²
A² - B² = C²
A + B = C²
A/B = C

The correct answer is: A² + B² = C²

The Pythagorean theorem is an essential principle in geometry that relates the lengths of the sides of a right triangle. The theorem states that the square of the length of the hypotenuse (the side opposite the right angle, often referred to as side C) is equal to the sum of the squares of the lengths of the other two sides (commonly referred to as sides A and B). This relationship is represented by the formula A² + B² = C². In this formula, A and B are the lengths of the two legs of the right triangle, while C is the length of the hypotenuse. This theorem is fundamental in various fields, including mathematics, physics, engineering, and architecture, as it provides a straightforward method to calculate distances and relationships in right-angled triangles. The other options do not convey the correct relationship among the sides of a right triangle as outlined by the Pythagorean theorem. Thus, the formula A² + B² = C² accurately embodies this vital mathematical concept.
