Pythagoras theorem is the relation among the hypotenuse and the other two sides of a right triangle:

In any right triangle, the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares whose sides are the two legs (the two sides that meet at a right angle).
