Pythagoras was a Greek philosopher and mathematician considered the first pure mathematician. He contributed significantly to the advancement of Hellenic mathematics, geometry, arithmetic, derived particularly from numerical relationships, and applied for example to the theory of weights and measures, to music theory or astronomy. He is the founder of the Pythagorean School, a society that, although predominantly religious in nature, was also interested in medicine, cosmology, philosophy, ethics and politics, among other disciplines.
PYTHAGOREAM THEOREM
First we should remember a couple of ideas:
- A right triangle is a triangle that has a right angle, that is 90º.
- In a right triangle, the large side is called hypotenuse and the other two sides are called catetos.
- In a right triangle, the square of the hypotenuse is equal to the sum of the squares of the catetos.
