Which special version of the Pythagorean Theorem can you use to find the length of any square's diagonal, d, using only the length of its side, s?

is this a^2+b^2=c^2?

yes, but you are dealing with a square, where a=b. Plug that in and see what you get.

(leg)^2 + (leg)^2 = (hypotenuse)^2

Let leg = s

Let d = hypotenuse

s^2 + s^2 = d^2

2s^2 = d^2

sqrt{2s^2} = sqrt{d^2}

s•sqrt{2} = d

You can use d = s•sqrt{2} to find the length of a diagonal of any square.

I hope this helps.
