Polygons In Higher Dimensions. The word “polygon” usually refers specifically to 2-dimensional shapes that are made out of straight lines. The concept of a polygon can be generalized to higher dimensions.The generalization of a polygon is called a polytope.So a polygon is a specific 2-dimensional instance of the more general idea of a polytope.

Polygons are classified mainly into four categories. They are: Regular polygon – all the sides and measure of interior angles are equal Irregular polygon – all the sides and measure of interior angles are not equal, i.e. different Convex polygon – all the interior angles of a polygon are strictly less than 180 degrees. The vertex will point outwards from the centre of the shape Concave ...

For polygons with 3 through 20 sides, simply add "gon" to the prefixes at the left (although a trigon is more commonly called a triangle and a tetragon, a quadrilateral!). For more than 20 sides, we "construct" the name by using so-called combining prefixes:
