Polygons - Concept

Concept Concept (1)

Polygons are closed plane figures formed by three or more line segments. If a figure is open or curved, it cannot be considered a polygon. Concave polygons have at least one diagonal that does not pass through the interior of the polygon; all of the diagonals in a convex polygon are contained within the figure. Equiangular polygons have all angles congruent; equilateral polygons have all sides congruent.
