A polygon is a union of disjoint line segments that is path-connected.

A polygon is described as "regular" if all its sides and their included angles are equal.

Types, by number of sides.

There is no such mathematical entity as a one sided polygon in a plane. (For higher 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 - three sided, see isosceles triangle, equilateral triangle, right triangle
Quadrilateral - four sided, see also square, rectangle, rhombus, and trapezoid
Pentagon - five sided. The most famous one houses the Department of Defense.
Hexagon - six sided, the shape of a bee hive cell, also used in some board games
Heptagon - seven sided. Some coins have been been heptagonal.
Octagon - eight sided, used for stop signs in the U.S.
