The ratio of the areas of two similar triangles is equal to the ratio of the squares of their corresponding sides. In a right triangle, the square on the hypotenuse is equal to the sum of the squares on the other two sides. In a triangle, if the square on one side is equal to the sum of the squares on the other two sides, the angle opposite to the first side is a right angle.
