What is the theory of the Pythagorean Theorem?

Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.

Who proved the Pythagorean theorem first?

Euclid was the first to mention and prove Book I, Proposition 47, also known as I 47 or Euclid I 47. This is probably the most famous of all the proofs of the Pythagorean proposition.

What’s the Paragathem theory?

The Pythagorean equation relates the sides of a right triangle in a simple way, so that if the lengths of any two sides are known the length of the third side can be found. Another corollary of the theorem is that in any right triangle, the hypotenuse is greater than any one of the other sides, but less than their sum.

Why Pythagorean theorem is important?

The discovery of Pythagoras’ theorem led the Greeks to prove the existence of numbers that could not be expressed as rational numbers. For example, taking the two shorter sides of a right triangle to be 1 and 1, we are led to a hypotenuse of length , which is not a rational number.

What is Pythagoras theorem used for?

The Pythagorean Theorem is a useful tool that shows how the sum of the areas of three intersecting squares can determine the side lengths of a right triangle. This theorem is an extremely useful tool that provides the basis for more complex trigonometry theories such as the converse of the Pythagorean theorem.

Why is it called Pythagorean Theorem?

The Pythagorean Theorem is named after Pythagoras of Samos , a mathematician who was also a religious leader, and believed that all things in the universe were composed of numbers. (There are many different ways to prove this.) The hypotenuse of a right triangle is the side opposite the right angle.

Why was Pythagorean Theorem invented?

The Egyptians wanted a perfect 90-degree angle to build the pyramids which were actually two right-angle triangle whose hypotenuse forms the edges of the pyramids. There are some clues that the Chinese had also developed the Pythagoras theorem using the areas of the sides long before Pythagoras himself.
