Heron’s Formula for Triangular Area - University of …

Web(A quick proof of Heron’s formula is by using Pythagoras’ theorem cos2C+sin2C= 1, and cosine and sine rules: cosC= (a2+b2−c2)/(2ab) and sinC= 2S/(ab).) Now, from the basic Fibonacci recurrence F n+1 = F n+F n−1, it follows that the triangle whose side lengths are these numbers is degenerated. Hence, its area Sis zero. By Heron’s formula, Webhalf perimeter s=(a+b+c)/2, this result can also be written as Heron’s Formula- Area = s(s −a)(s −b)(s −c) The polymath Heron of Alexandria(approx. 10-70 AD)gave a rather complicated geometrical proof of this formula. It may not be original with him since many of his text references were to earlier Babylonian mathematicians.
