The Pythagoreans found that in 3-4-5 triangles, the area of the square of the hypotenuse equals the sum of the areas of the squares of the other two sides. They then generalized this rule for 3-4 ...

What it means is that in a right triangle (where one angle equals 90°), the sum of the squares of two sides equals the square of the hypotenuse (the longest side).
