Have friend heard about a polygon? Well, **polygons are all about us!** most of the common shapes the you check out or research every day room polygons. You view a wall, i beg your pardon is rectangular in shape, is a polygon.

You are watching: Which figure is not completely constructed from polygons

A front view of a dice, which has a square shape, is a polygon. A pizza part is triangular in shape, hence, a polygon.

**In this article, you will learn:**

## What is a Polygon?

**In mathematics, a polygon is a close up door two-dimensional figure consisted of of line segments however not curves. The ax polygon originates indigenous the Greek indigenous “poly -” an interpretation “many” and also “- gon,” an interpretation “angles.” **

The most common examples that polygons space the triangle, the rectangle, and the square. In an easy words, polygons are plain numbers or shapes comprised of heat segments only.

**Note:** Circles, three-dimensional objects, any kind of shapes that incorporate curves, and also any forms that aren’t closed space not polygons.

Polygons were well-known to humans since ancient times. **Greeks studied non-convex consistent polygon in 7th century BC** ~ above a krater by Aristophanes. Thomas Bradwardine was the an initial known person to examine non-convex polygon in the 14th century. The ide of polygon was generalized in 1952 through Geoffrey Colin.

Now that you have understood what a polygon is let us explore the different polygons and how lock look.

## Types of Polygons

Depending on the sides and angles, the **polygons space classified into** various types, namely,

### Regular Polygon

A constant polygon is a polygon in which all the interior angles are equal, and also also, all the sides room equal. There room different varieties of constant polygons.

*These are:*

**A triangle**: An it is intended triangle is a continuous polygon with 3 equal next lengths and also three same angles.

The following are a couple of mnemonics to assist remember the surname of part polygons:

A QuadBike has actually 4 wheels and thus a quadrilateral.The Washington DC in the US has actually 5 political parties (Pentagon).A**H**oneycomb has actually 6 sides (

**H**exagon).

**S**eptagon has actually 7 sides (

**S**even).An Octopus has actually 8 tentacles (octagon).The state

**N**onagon and also

**N**ine both start with the letter N.A

**Decagon**has actually 10 sides, similar to a

**D**ecimal suggest has 10 digits.

### Real-life applications that polygons

Understanding shapes is crucial in geometry. Shapes have actually a large application in real-life applications.

*For example:*

*Example*

John has a rectangular item of paper. He desires to reduced the record so the he gets two much more polygons (other than a rectangle) of the same size and also shape. Indicate the possible ways.

Solution

There are two possible ways to cut a rectangular piece of document in together a method that he it s okay two an ext polygons (other than a rectangle) that the very same size and shape:

He can reduced a rectangular piece of record exactly native the facility vertically to get the 2 squares that the very same size and also shape.He can cut a rectangular item of record diagonally to obtain the 2 triangles the the exact same size and shape.See more: How Much Does A Gallon Of Tea Weigh ?
