Symbolic Computation

Definition

The Pythagorean Theorem is a fundamental principle in geometry that establishes a relationship between the sides of a right triangle. Specifically, 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 theorem not only serves as a basis for many geometric proofs but also applies to various real-world situations involving distance and measurement.
