A polygon is a closed plane (2-D) figure having three or more straight sides that intersect only at the vertices. Polygons have the same number of sides as vertices. Polygons are identified by their number of sides.
A regular polygon has equal sides and equal angles. An irregular polygon is a polygon whose sides are not all the same length. A circle is not a polygon because it does not have straight line segments.
The following table gives the names of some polygons and examples of regular polygons and irregular polygons. Scroll down the page for more examples, songs and explanations about polygons.
