Answer 7

The above is correct. To prove this is a square, you need to prove that the perpendicular side is 17 inches.

You have two lengths of a right angled triangle, so Pythagoras' theorem is the way to go.

c^2 (the diagonal squared) = a^2 (one length squared) + b^2 (the other length squared)

Try substituting your values into that equation
