Pythagorean Theorem

from class:

Ancient Greece

Definition

The Pythagorean Theorem is a fundamental principle in mathematics that establishes a relationship between the sides of a right triangle. Specifically, it states that 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, expressed as $$a^2 + b^2 = c^2$$. This theorem not only serves as a crucial tool in geometry but also highlights the advancements in mathematical understanding during ancient Greek civilization.
