The diagram shows squares 1,2 and 3 constructed on the sides of a right triangle. which statement about the squares must be true?

For this question, you have to use the Pythagorean theorem, which states: a2 + b2 = c2, where c is the hypotenuse. Since the area of a square is its length squared, we can see in the diagram that the area of square 3 is therefore the sum of the area of square 1 and the area of square 2. I don’t know if thats a clear explanation but i hope it helps :)

Your answer should be 1/3. i hope i could ! good luck : )
