Polygons are 2-dimensional shapes. They are made of straight lines, and the shape is "closed" (all the lines connect up).
Regular or Irregular
A regular polygon has all angles equal and all sides equal, otherwise it isirregular
Concave or Convex
A convexpolygon has no angles pointing inwards. More precisely, no internal angle can be more than 180°. If any internal angle is greater than 180° then the polygon is concave. (Think: concave has a "cave" in it)
Simple or Complex
A simple polygon has only one boundary, and it doesn't cross over itself. A complexpolygon intersects itself! Many rules about polygons don't work when it is complex.
Quadrilateral
A QuadBike has 4 wheels
Pentagon
The "Pentagon" in Washington DC has 5 sides
Hexagon
