Shoelace Formula: Connecting the Area of a Polygon and the Vector Cross Product
Lee, Younhee; Lim, Woong
Mathematics Teacher, v110 n8 p631-636 Apr 2017
Understanding how one representation connects to another and how the essential ideas in that relationship are generalized can result in a mathematical theorem or a formula. In this article, the authors demonstrate this process by connecting a vector cross product in algebraic form to a geometric representation and applying a key mathematical idea from the relationship to prove the Shoelace theorem.
