Here’s the idea: Suppose you have a two-dimensional polygon, where the vertices are identified by their -coordinates: The shoelace formula found here or here tells you how to calculate the area of any polygon given its coordinates. The second link I mentioned gives a proof of it, but it is a bit beyond my level of comprehension. Could anyone try to simplify the proof (or provide their own) to a level up to and including single variable calculus? Method 4: Shoelace Theorem Also known as \Shoelace Formula," or \Gauss’ Area Formula" Shoelace Theorem (for a Triangle) Suppose a triangle has the following coordinates: (a 1;b 1), (a 2;b 2), (a 3;b 3) where a 1;a 2;a 3;b 1;b 2; and b 3 can be any positive number. Then, A 3 = 1 2 2 a 1 b 1 a b 2 a 3 b 3 a 1 b 1 = where jajis called the The shoelace algorithm Green’s theorem can also be used to derive a simple (yet powerful!) algorithm (often called the “shoelace” algorithm) for computing areas. Here’s the idea: Suppose you have a two-dimensional polygon, where the vertices are identified by their -coordinates: The shoelace formula, or shoelace algorithm, is a mathematical algorithm to determine the area of a simple polygon whose vertices are described by ordered pairs in the plane. The user cross-multiplies corresponding coordinates to find the area encompassing the polygon, and subtracts it from the surrounding polygon to find the area of the polygon within.

The shoelace formula or shoelace algorithm is a mathematical algorithm to determine the area of a simple polygon whose vertices are described by their Cartesian coordinates in the plane. The method consists of cross-multiplying corresponding coordinates of the different vertices of a polygon to find its area. It is called the shoelace formula because of the constant cross-multiplying for the
The shoelace algorithm Green’s Theorem can also be used to derive a simple (yet powerful!) algorithm (often called the “shoelace” algorithm) for computing areas. Here’s the idea: Suppose you have a two-dimensional polygon, where the vertices are identified by their -coordinates: The vertices of triangle ABC are A(0,0), B(-1,-7) and C(-3,2). Calculate the area of triangleABC. 2020-4-17 · Determinants, Shoelace Formula Shoelace Formula Let s be an ordered set of points in the plane that defines a simple closed polygon. A segment joins the first point in s to the second, then another segment joins the second to the third, and so on, just like dot-to-dot. The shape is closed as a segment joins the last point to the first. Figure 1: Diagram of the Tetrahedral Shoelace Method.
