In geometry, there are kinds of polygons which can be classified as the simplex or complex polygon, concave or convex polygon and regular or irregular polygon. There are many types in the regular polygons such as quadrilateral, pentagon, Hexagon, Heptagon, Octagon, Nonagon, Decagon etc. Now we are going to see about the kinds of polygons in geometry.

**Kinds of Polygons in Geometry:**

In geometry, there are numerous types of polygons and they are explained as below

**Simple or Complex:**

A simple and a complex polygon has one boundary only. simple polygons don’t cross each other but the complex intersects by itself.

**Concave or Convex:**

A convex polygon has no internal angles and they will not be more than 180°. If the internal angles are more than 180° then it is called as concave.

**Regular and irregular polygon:**

The regular polygon contains all the shapes and the angles are equal and in irregular it is not equal.

**Other Kinds of Polygons in Geometry:**

1. Equiangular polygon : In this polygon, all the corner angles in it are equal in its length and its measurements..

2. Cyclic polygon: In this polygon, all the corners of the polygon lie on a single circle plane.

3. Equilateral polygon: In this equilateral polygon, all the edges are having the same length.

The other types of polygons are explained as follows,

**Triangle:**

The triangle is a 3 sided figure and the sum of the triangles will be 180 degrees.

**Quadrilateral:**

The quadrilateral is a four sided figure and the sum of the angles will be 360 degrees

**Pentagon:**

The pentagon is a five sided figure and all the sides are having different lengths in its measurement

**Hexagon:**

Hexagon consists of six sides and it is a type of polygon

**Heptagon:**

The heptagon is a type of polygon consists of seven sides and seven vertices.

**Octagon:**

The octagon is contains 8 sides are equal and the internal angles are 135 degrees

**Nonagon:**

The nonagon contains 9 sides and the angles are equal

**Decagon:**

The decagon consists of ten sides and the angles are equal
