Osnova geometrije, kvadrat nad hipotenuzom pravouglog trougla je jednak zbiru kvadrata nad katetama.
U pravouglom trouglu kvadrat nad hipotenuzom jednak je zbiru kvadrata nad obema katetama: Pitagora: veliki starogrčki filozof (582-500 g. pre n.e.)

Pythagorean theorem
IPA: / paɪˌθæɡʌˈriːən ˈθɪrəm /In geometry, a theorem stating that in a right triangle, the area of the square on the hypotenuse (the longest side) is equal to the sum of the areas of the squares drawn on the other two sides. If the hypotenuse is h units long and the lengths of the other sides are a and b, then h2 = a2 + b2.
The theorem provides a way of calculating the length of any side of a right triangle if the lengths of the other two sides are known. It is also used to determine certain trigonometrical relationships such as sin2 q + cos2 q = 1.
