Taksonomi klasifikasi poligon ditunjukkan melalui gambarajah di bawah:

                                      Polygon                                     /       \                                 Simple     Complex                                /      \      /                           Convex    Concave /                            /    \     /    /                       Cyclic    Equilateral                           \     /                               Regular

• A polygon is called simple if it is described by a single, non-intersecting boundary (hence has an inside and an outside); otherwise it is called complex.
• A simple polygon is called convex if it has no internal angles greater than 180°; otherwise it is called concave or non-convex.
• A simple polygon is called equilateral if all edges are of the same length. (A 5 or more sided polygon can be concave and equilateral)
• A convex polygon is called concyclic or a cyclic polygon if all the vertices lie on a single circle.
• A cyclic and equilateral polygon is called regular; for each number of sides, all regular polygons with the same number of sides are similar.
• A simple polygon may also be defined as regular if it is cyclic and equilateral.
