This letter is the final one in the series of three letters that I wrote to my nephew during the covid lockdown. In this letter I tell him a surprising fact. If x, y and z are the sides of a right-angled triangle with z the length of the hypotenuse with all of them positive integers with gcd (x, y, z) = 1 then z must surely be an odd integer.
