A polygon is a union of disjoint line segments that is path-connected.
Types, by number of sides.
- There is no such mathematical entity as a one sided polygon in a plane. (For three dimensional analogies, see Mobius strip and Klein bottle.)
- As with the one-sided polygon, there is no such thing as a two-sided polygon. (This would be two overlapping line segments.)
- Triangle - see isosceles triangle, equilateral triangle, right triangle
- Quadrilateral: See also square and rectangle
- Pentagon
- Hexagon - the shape of a bee hive cell, also used in some board games
- Heptagon - not commonly encountered in everyday life
- Octagon - used for stop signs in the U.S.
