Have you heard about a polygon? Well, these figures are all over us! The majority of the common forms that you see or research each day are polygons. You see a wall surface, which is rectangle-shaped in shapes are polygons.

**In this post, you will discover:**

What polygons are, and also how do they appear like.

**The different kinds of polygons.**

In math, a polygon is a shut two-dimensional number composed of line sections, however not curves.

One of the most common polygons is the triangle, the rectangle, and the square. In essential words, polygon is plain figures or forms comprised of line sectors just.

**Note**: Circles, three-dimensional things, any shapes that include curves, as well as any shapes that aren’t shut are not polygon.

Polygon are understood by people considering that ancient times. Greeks examined non-convex regular polygon in 7th century BC on a krater by Aristophanes. Thomas Bradwardine was the first known individual to examine non-convex polygons in the 14th century.

Since you have understood what a polygon is, let us explore the various polygons and how they look.

**Types of Polygons.**

Depending upon the sides and angles, the polygon is identified into various kinds, specifically.

- Regular Polygon.
- Irregular Polygon.
- Convex Polygon.
- Concave polygon.
- Normal Polygon.

A regular polygon has all the interior angles equal, as well as likewise, all the sides are equivalent. There are different kinds of regular polygon.

**These are:**

**A triangle**: An equilateral triangle with three equivalent side sizes and also three equal angles.

**A quadrilateral.** It is a regular polygon with four angles and also four sides. Examples of quadrangles are.

**A square:** A quadrilateral whose four walls or sides are equal and four angles are all 90 degrees each.

**Parallelogram:** Opposite sides are parallel, contrary sides are equivalent in length, unorthodox angles are equal.

**Kite:** 2 pairs of nearby sides are of equal length; the shape has an axis of balance.

**Rhombus**: An unique type of parallelogram in which all four sides are the same size, like a square that has squashed sidewards.

**Hexagon:** A regular polygon that has six identical sides as well as six equal angles.

**Heptagon:** A regular polygon with seven equivalent side lengths as well as seven very same angles.

**Octagon:** An octagon has eight parallel sides and also eight equivalent angles.

**Nonagon: Has nine equal sides and also nine very same angles.**

**Hendecagon:** Has 11 equal sides and 11 equivalent angles.

**Dodecagon:** a regular polygon with 12 equivalent sides as well as 12 same angles.

**Triskaidecagon:** Has 13 equivalent sides and 13 very same angles.

**Tetrakaidecagon**: Has 14 equivalent sides as well as 14 same angles.

**Hexakaidecagon**: has 16 sides as well as angles.

**Heptadecagon:** Has 17 sides and angles.

**Octakaidecagon:** Has 18 sides as well as angles.

**Enneadecagon**: 19 sides as well as 19 angles.

**Irregular polygon.**

An irregular polygon is a polygon with the different step of angles and also side lengths.

**Examples of irregular polygon.**

**Convex Polygon.**

This is a sort of polygon with all the indoor angles purely less than 180 degrees. The vertex of a convex polygon always aims outwards from the centre of the shape.

**Concave Polygon.**

If several indoor angles of a polygon are more significant than 180 degrees, it is called a concave polygon. A scooped polygon can contend the very least four sides– the vertex points in the polygon’s direction.

The following are a few to help keep in mind the names of some polygons.

- A QuadBike has four wheels as well as hence a quadrilateral.
- The Washington DC in the United States has five sides.
- An Octopus has eight tentacles (octagon).
- Septagon has seven sides (Seven).
- A Honeycomb has six sides (Hexagon).

**Real-life applications of polygons.**

Understanding shapes is necessary for geometry. Shapes have an extensive application in real-life applications.

**For Example.**

The tiles that you stroll on are settled fit, which suggests that they are polygons.

- The truss of a structure or bridge, the walls of a building, etc., are examples of polygons.
- Trusses are triangular fit, while wall surfaces are rectangle-shaped formed.
- The rectangular-shaped screen of your laptop computer, tv, or smartphone is an example of a polygon.
- The Pyramids of Egypt are additionally an example of polygons (triangular).
- Star-shaped figures are examples of a polygon.
- Road signs are likewise an example of polygons.
