What were the major contributions of Ancient Greece to mathematics and geometry?

Ancient Greece made significant contributions to mathematics and geometry. Some of the major contributions include:

1. Euclidean Geometry: The Greek mathematician Euclid developed the foundational principles of geometry in his work "Elements." This book laid out the fundamental concepts, definitions, and proofs of geometry that are still studied today.

2. Pythagorean Theorem: The Pythagorean theorem, which states that in a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides, was discovered by the Greek mathematician Pythagoras.

3. Mathematical Proof: Ancient Greeks emphasized the importance of rigorous mathematical proof. They developed logical reasoning and deductive methods to prove mathematical theorems, which became the basis for modern mathematical proofs.

4. Calculating Pi: Ancient Greeks made significant progress in calculating the value of pi (π). Archimedes, a Greek mathematician, developed a method to approximate pi using polygons, which was a significant advancement in understanding the ratio of a circle's circumference to its diameter.

5. Number Theory: Greek mathematicians, such as Euclid and Pythagoras, made important contributions to number theory. They explored properties of prime numbers, divisibility, and the concept of perfect numbers.

6. Mathematical Notation: Ancient Greeks introduced symbols and notation to represent mathematical concepts. For example, they used letters of the Greek alphabet to represent unknowns in equations, a practice that is still followed today.

Overall, Ancient Greece's contributions to mathematics and geometry laid the foundation for many of the mathematical principles and concepts that are still used and studied in modern times.
