What is the Pythagorean Theorem used to calculate?

The Pythagorean Theorem specifically relates to the relationship between the sides of a right triangle. It states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. This relationship can be expressed mathematically as (a^2 + b^2 = c^2), where (c) represents the length of the hypotenuse, and (a) and (b) represent the lengths of the other two sides.

This theorem is fundamental in geometry and is widely used to determine lengths within right triangles, making it essential for solving various practical problems in multiple fields such as architecture, engineering, and physics. Understanding this relationship helps students apply the theorem to find unknown side lengths when given certain information about a right triangle.

In contrast, the other provided choices pertain to different geometric concepts. The area of a circle involves different formulas, the sum of angles in a triangle relates to angle measurements, and the lengths of the sides of a triangle encompasses more than just right triangles, which does not narrow focus to the Pythagorean Theorem.
