Pythagoras

Definition

Pythagoras was an ancient Greek philosopher and mathematician, best known for his contributions to geometry, particularly the Pythagorean theorem, which describes the relationship between the sides of a right triangle. His ideas laid the groundwork for many mathematical principles and introduced the concept of numbers as fundamental to understanding the universe, linking mathematics with philosophy and deductive reasoning.
