Proof that the Area of a Triangle = bh/2

Fermat’s Last Theorem: xn + yn = zn has no positive integral solutions for n>2. Proven recently by Andrew Wiles (omitted here for lack of room in the margin). Hypotenuses in a “square root spiral” are of length sqrt 2, sqrt 3, sqrt 4, sqrt 5,… (Inductive proof) The square root of 2 is irrational. ................
