Heron's theorem
WitrynaThis can also be written in form of a summation or in terms of determinants as which is useful in the variant of the Shoelace theorem. Note here that and . The formula may also be considered a special case of Green's Theorem where and so . Proof 1. Claim 1: The area of a triangle with coordinates , , and is . Proof of claim 1: WitrynaWhich is just another way of writing Heron's formula. Thus, the two facts: Pythagoras' Theorem and Heron's formula each have an independent proof. But, in addition, each can be derived from the other. Remark Dr. S. Brodie has kindly prepared a demonstration of how Pythagoras' Theorem is used to construct a regular pentagon.
