Now is an appropriate time to reveal that the actual formula is d ≈ s√2. (To convince them that this is the case, you may wish to have students use this formula to determine the length of the diagonal for several squares and compare the results to actual measurements. ... Explore irrational numbers, namely square roots.

Now, if we use Pythagoras’ theorem, the diagonal of a square forms with two of the sides a right angled triangle, and if we take the sides to have length one, the length of the diagonal squared equals 1 + 1, so the length of the diagonal is the square root of 2. The figure on the clay tablet is incredibly...
