A polygon is a closed plane figure formed by three or more segments that intersect only at their endpoints Each segment that forms a polygon is a side of the polygon The common endpoint of two sides is a vertex of the polygon A segment that connects any two nonconsecutive vertices is a diagonal You can name a polygon by the number of its sides

Chapter 3 –Polygons and Quadrilaterals

No matter the type of polygon you are working with, the sum of all of the interior angles will always add up to one constant value This value depends on the number of sides a polygon has For example, any four sided polygon will always have interior angles that add up to 360˚ no matter if it is a regular (square) polygon, or an irregular polygon

A characterization of regular polygons

For the understanding of a convex polygon, we will need the following Jordan Curve Theorem for Polygons,whichisTheorem4 13onpage195ofRNLE Theorem 4 13 The complement of a polygon consists of two non-empty planar regions, and with the following properties: *I wish to thank Larry Francis for his excellent editorial assistance 1
