Pythagoren Theorem Pythagoras' Theorem: Given a right triangle with sides a and b and a hypotenuse h (the side opposite the right angle). Then, Remember that... triangle is a right-angled triangle because it has a right angle, an angle of 90º or π / 2 radians The hypotenuse is the opposite side as the right angle. Note: h is always bigger than the other sides, as shows h > a and h > b. The Pythagoras theorem is one of the most known results in mathematics and also one...

These pages aim to present some of the most important mathematical problems in chronological order. It is not intended to be an exhaustive explanation of each problem but to simply show the evolution of mathematical thought throughout history. In each section there is an outline of the most relevant historical events of the era and the maps indicate the area of interest, both from a mathematical point of view.
