What is the Meaning & Definition of the theorem of Pythagoras

It is called a theorem to that proposition that is plausible to be demonstrated logically and from an axiom, or in their absence, of other already proven theorems, meanwhile, turns out to be necessary to observe certain rules of inference to get the aforementioned show.
On the other hand, Pitágoras of Samos was a popular philosopher and mathematician Greek who lived in Greece between 582 and 507 BC Although it bears its name in his honor for having given the necessary conditions so that it finally found a demonstration, the Pythagorean theorem was not created directly by Pythagoras but that in reality it was developed and applied a long time before both Babylon and India, though, it was the school of Pythagoras who managed to find a formal and forceful response to the theorem.
Meanwhile, the mentioned theorem says that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the legs. To better understand the issue it is necessary to note that a right triangle is one who has a right angle that measures 90 °, then the hypotenuse is the side of the triangle which has one greater length and which directly opposes the right angle and finally Hicks are the two smaller right triangle sides.
It should be noted, that the theorem that we are discussing is which has more amounts of shows and they were made from very different methods.
In the 20th century, more precisely in the year 1927, a mathematician, E.S. Loomis collected more than 350 demonstrations of the Pythagorean theorem, which brought a little more order on the subject, they were classified into four groups: geometric demonstrations (are made on the basis of the comparison of areas), algebraic demonstrations (are developed on the basis of the relationship between the sides and the segments of the triangle) , dynamic demonstrations (summon the strength properties) and cuaternionicas shows (listed by the use of vectors).
