Polygons - A polygon is a closed figure where the sides are all line segments. Each side must intersect exactly two others sides but only at their endpoints. The sides must be noncollinear and have a common endpoint. A polygon is usually named after how many sides it has, a polygon with n-sides is called a n-gon.
Examples:
Triangle - 3 sides
Quadrilateral- 4 sides
Pentagon- 5 sides
Hexagon - 6 sides
Heptagon - 7 sides
Octagon- 8 sides
Nonagon- 9sides
Decagon- 10 sides
Types of Polygons
Regular or Irregular
A regular polygon has all angles equal and all sides equal, otherwise it is irregular
Simple or Complex
A simple polygon has only one boundary, and it doesn't cross over itself. A complex polygon intersects itself! Many rules about polygons don't work when it is complex.
