Greek philosopher and mathematician
570 – 495 BC
Pythagoras was a Greek philosopher and mathematician who lived in the 6th century BC. He is best known for the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Early life
Pythagoras was born on the island of Samos in the Aegean Sea. He is said to have been a brilliant student, and he traveled to many different parts of the world to learn from the leading philosophers and mathematicians of his day.

The Pythagorean brotherhood
In Croton, Italy, Pythagoras founded a school known as the Pythagorean brotherhood. The members of the brotherhood were devoted to the study of mathematics, music, and philosophy. They also lived a strict communal lifestyle, and they were required to keep their teachings secret.

Pythagoreanism
The philosophy of Pythagoras, known as Pythagoreanism, had a profound influence on later Greek thought. It was based on the belief that the universe is governed by mathematical principles. Pythagoreans also believed in the transmigration of souls, the idea that the soul is reborn after death into a new body.

Later life
Pythagoras is said to have died in a political uprising in Croton. However, his teachings continued to be influential for centuries to come. They had a major impact on the development of Western philosophy, mathematics, and science.

Legacy
Pythagoras is considered one of the most important figures in the history of Western thought. His contributions to mathematics, music, and philosophy have had a lasting impact on our understanding of the world.
Here are some of the Pythagorean contributions to mathematics and science:

The Pythagorean theorem
The discovery of the five regular solids
The development of the theory of proportions
The Pythagorean school was the first to introduce the idea of a mathematical proof.
The Pythagoreans also made important contributions to the study of music. They discovered that the pitch of a note is determined by the length of the string that produces it. They also developed the theory of musical harmony.

The Pythagorean philosophy had a profound influence on later Greek thought.

It was based on the belief that the universe is governed by mathematical principles.
Pythagoreans also believed in the transmigration of souls, the idea that the soul is reborn after death into a new body.

Pythagorean theorem

Introduction
The Pythagorean theorem is one of the most famous theorems in mathematics. It states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
History
The Pythagorean theorem is named after Pythagoras, a Greek philosopher and mathematician who lived in the 6th century BC. However, the theorem was known long before Pythagoras's time. It was first discovered by the Babylonians in the 2nd millennium BC.
Proof
There are many different ways to prove the Pythagorean theorem. One of the most common proofs is the following:

Draw a right triangle with legs of length a and b and hypotenuse of length c.
Draw a square with sides of length a + b.
Divide the square into four right triangles, each with legs of length a and b and hypotenuse of length c.
The area of the square is (a + b)^2.
The area of each right triangle is (1/2)ab.
The area of the square is equal to the sum of the areas of the four right triangles.
Therefore, (a + b)^2 = 4(1/2)ab.
Simplifying both sides of the equation, we get a^2 + 2ab + b^2 = 2ab.
Subtracting 2ab from both sides of the equation, we get a^2 + b^2 = c^2.

Applications
The Pythagorean theorem has many applications in mathematics, science, and engineering. For example, it can be used to:

Find the length of the hypotenuse of a right triangle.
Find the distance between two points on a map.
Calculate the area of a triangle.
Determine whether a triangle is right, obtuse, or acute.

Conclusion
The Pythagorean theorem is a powerful tool that can be used to solve a variety of problems. It is one of the most important theorems in mathematics, and it has many applications in science, engineering, and everyday life.
Here are some other interesting facts about the Pythagorean theorem:

The Pythagorean theorem is the first theorem in mathematics that has a formal proof.
The Pythagorean theorem can be used to derive many other mathematical formulas, such as the formula for the area of a triangle.
The Pythagorean theorem has been used in architecture for centuries. For example, it was used to build the pyramids in Egypt.
The Pythagorean theorem is even used in music. For example, it can be used to calculate the frequencies of different notes.

The Pythagorean theorem is a truly remarkable theorem that has had a profound impact on our understanding of the world.
