To compute the centroid of the whole polygon, we just have to compute the average of the centroids of the constituent triangles, with each triangle weighted by its (signed) area. What makes this task especially easy for a polygon is that we can allow ourselves to include "negative" triangles...

A way that allows students to discover a strategy for determining the area of rectangles, squares, parallelograms, triangles, and trapezoids is described. Students use grid paper and scissors to determine the number of square units that cover a specified space. (KR)...
Finding the perimeter of polygons means that the distance that is all around the shape has to be found. Study the definition of polygons and the perimeter, and how to use a shortcut to find the perimeter for regular polygons. Polygons Polygons, flat shapes with straight sides, are very...
In summary, if a regular polygon has n number of sides, the exterior angles between the sides will be in an orderly progression, starting with 120° and ending at 72°. The total measure of the angles in the n-1 vertices will be the sum of the measures in the n- s...
Choose an option in the Search Goal area to indicate the types of features you want to find. Only Multiple Parts—Only finds polygons that have multiple parts. Polygons with holes are omitted from the results. This is the default option. Note: When running this check in a Reviewer batch...
If necessary, click theSeveritydrop-down arrow and choose a value that indicates the priority of the check's results in the Reviewer Remarks area. The severity indicates the importance of the check result. The values range from 1 to 5, with 1 being the highest priority and 5 being the low...
Institute of Science, Rehovot 76100, Israel Communicated by Anna Lubiw and Jorge Urrutia; submitted 22 November 1993; accepted 27 September 1994 Abstract This paper considers the geometric optimization problem of finding the Largest area axis-parallel Rectangle (LR) in an n-vertex general polygon. ...
Its slightly unclear if you would like to find the largest possible shape amongst all the points. However, provided you now have the points that you have the perimeter points to each shape, you can compute the area of each shape in linear time using theShoelace Theorem: ...
We consider the following geometric optimization problem: find a maximum-area rectangle and a maximum-perimeter rectangle contained in a given convex polygon with n vertices. We give exact algorithms that solve these problems in time O(n3). We also give (1−ε)-approximation algorithms that tak...
