## What is an example of a polygon shape?

Triangles, hexagons, pentagons, and quadrilaterals are all examples of polygons. The name gives an indication of how many sides the shape has. For example, a triangle consists of three sides while a quadrilateral consists of four sides.

## What is a polygon shape?

In geometry, a polygon can be defined as a flat or plane, two-dimensional closed shape bounded with straight sides. It does not have curved sides. The sides of a polygon are also called its edges. The points where two sides meet are the vertices (or corners) of a polygon.

## What are the 10 polygons?

Types of Polygons
• 3 sides – Triangle.
• 5 sides – Pentagon.
• 6 sides – Hexagon.
• 7 sides – Heptagon.
• 8 sides – Octagon.
• 9 sides – Nonagon.
• 10 sides – Decagon.

## What is polygon and example?

polygon, in geometry, any closed curve consisting of a set of line segments (sides) connected such that no two segments cross. The simplest polygons are triangles (three sides), quadrilaterals (four sides), and pentagons (five sides).

## Is a square a polygon?

A square is a regular polygon having four equal sides and equal angles that measure 90° each.

## What is the name of 20 sides of polygon?

In geometry, an icosagon or 20-gon is a twenty-sided polygon. The sum of any icosagon’s interior angles is 3240 degrees.

## What type of polygon has 12 sides?

dodecagon
A dodecagon is a 12-sided polygon. Several special types of dodecagons are illustrated above. In particular, a dodecagon with vertices equally spaced around a circle and with all sides the same length is a regular polygon known as a regular dodecagon.

## What type of polygon has 7 sides?

A heptagon is a seven-sided polygon. It is also sometimes called a septagon, though this usage mixes a Latin prefix sept- (derived from septua-, meaning “seven”) with the Greek suffix -gon (from gonia, meaning “angle”), and is therefore not recommended.

## What type of polygon has 7 sides?

A heptagon is a seven-sided polygon. It is also sometimes called a septagon, though this usage mixes a Latin prefix sept- (derived from septua-, meaning “seven”) with the Greek suffix -gon (from gonia, meaning “angle”), and is therefore not recommended.

## What is a regular polygon of 7 sides called?

A heptagon is a polygon that has seven sides. It is a closed figure having 7 vertices. A heptagon is also sometimes called Septagon.

## What is a 7 shape?

Heptagon is a polygon ( a closed shape made up of line segments) made up of 7 sides and 7 angles. The word heptagon is made up of two words, hepta meaning seven and gon meaning sides. There are 14 diagonals in a heptagon and in the given heptagon, the blue line segments represent the diagonals.

## How many polygons are there?

There are 4 types of Polygon : Regular Polygon: If all the sides and interior angles of the polygon are equal or if a polygon is equiangular and equilateral, then the polygon will be known as a regular polygon. Example square, rhombus, equilateral triangle, etc.

## What is an 8 sided polygon called?

octagon
An eight-sided shape is an octagon only if the shape is closed and made up of straight lines. What is the sum of the angles of an irregular octagon? The angles of the irregular octagon are unequal. Still, they measure up to a sum of 1080°.

## What is a 12 sided polygon?

## What is a 8 sided shape called?

An octagon is a shape with 8 sides and 8 angles.

## What is a 11 sided shape called?

hendecagon
A hendecagon is an 11 sided shape with 11 corners.

## What is a 9 sided polygon called?

enneagon
1. A nonagon is also called enneagon, which is derived from a Greek word called enneagonon, which means nine corners. 2. The first use of the word nonagon dates back to the early 17th century, and has a Latin prefix (nona) and a Greek suffix (gon), making it a polygon with nine sides and nine angles.

## What is a 9 sided object called?

A nonagon is a nine sided polygon and it is also called an Enneagon or 9-gon.

## What is a 20 sided polygon called?

The icosahedron – 20-sided polyhedron – is frequent. Most often each face of the die is inscribed with a number in Greek and/or Latin up to the number of faces on the polyhedron.
