# Is it possible to evaluate the exact diagonal length of a square using Pythagoras theorem?

That depends how exactly the measurements of the sides are - and how exactly the "right angle" is really a right angle. If the measurements are exact, then, yes, you can also calculate the diagonal exactly - using Pythagoras' Theorem.
