Proof that the Area of a Triangle = bh/2

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. (p/q) 2 = 2 ( p2 = 2q2, then apply Fundamental Theorem of Arithmetic ( lhs has even # of prime factors, rhs has odd #, QED. ................
