How many different types of polygons are there?
There are two main types of polygon – regular and irregular. A regular polygon has equal length sides with equal angles between each side. Any other polygon is an irregular polygon, which by definition has unequal length sides and unequal angles between sides.
What are the first 10 polygons?
Here is a list of polygon names depending on the number of sides they have, starting with three and ending with ten.
- 3 sides – Triangle.
- 4 sides – Quadrilateral.
- 5 sides – Pentagon.
- 6 sides – Hexagon.
- 7 sides – Heptagon.
- 8 sides – Octagon.
- 9 sides – Nonagon.
- 10 sides – Decagon.
What are polygons examples?
A polygon is any 2-dimensional shape formed with straight lines. Triangles, quadrilaterals, pentagons, and hexagons are all examples of polygons. The name tells you how many sides the shape has. For example, a triangle has three sides, and a quadrilateral has four sides.
What is the name of polygon has 11 sides?
List of n-gons by Greek numerical prefixes
| Sides | Names | |

What are the different types of pentagons?
Types of Pentagons
- Regular or equilateral pentagon: five equal sides and angles.
- Irregular pentagon: five unequal sides and unequal angles.
- Convex pentagon: no internal angle can be greater than 180 degrees.
- Concave pentagon: has an internal angle greater than 180 degrees causing two sides to “sink in” like a “cave”
What is a polygon with 11 sides?
hendecagon
In geometry, a hendecagon (also undecagon or endecagon) or 11-gon is an eleven-sided polygon. (The name hendecagon, from Greek hendeka “eleven” and –gon “corner”, is often preferred to the hybrid undecagon, whose first part is formed from Latin undecim “eleven”.)
What is a polygon with 8 sides?
octagon
In geometry, an octagon (from the Greek ὀκτάγωνον oktágōnon, “eight angles”) is an eight-sided polygon or 8-gon. A regular octagon has Schläfli symbol {8} and can also be constructed as a quasiregular truncated square, t{4}, which alternates two types of edges. A truncated octagon, t{8} is a hexadecagon, {16}.
What are the names of all the polygons?
Some polygon names include triangle, quadrilateral, pentagon, hexagon and septagonn. Most polygon names are derived from a Greek word referring to the number of sides a shape has. A polygon is a closed connection of line segments. Each line segment is called a side.
What are real life examples of polygons?
The tiles that you walk on are squared in shape,which implies that they are polygons.
What are the classifications of polygons?
Polygons – Classification. Regular polygons are named to indicate the number of their sides or number of vertices present in the figure. Thus, a hexagon has six sides, while a decagon has ten sides. Examples of regular polygons also include the familiar square and octagon. Not all polygons are regular or symmetric.
What are the three polygons?
By definition, a 3-sided polygon is a triangle . There are many different types of triangles. Equilateral. Isosceles. Scalene. Acute. obtuse. Right angled.
