A polygon is a plane shape with straight sides.
Polygons are 2-dimensional shapes. They are made of straight lines, and the shape is "closed" (all the lines connect up).
Polygon comes from Greek. Poly- means "many" and -gon means "angle".
Types of Polygons
Simple or Complex
A simple polygon has only one boundary, and it doesn't cross over itself. A complex polygon intersects itself!
