Pentagon: The closed figure which is formed by five straight lines is known as a pentagon. Hexagon: The six-sided polygon is known as a hexagon. Heptagon: The polygon with seven sides is termed as a heptagon. Octagon: As the name says, the Eight-sided polygon is known as Octagon.

Which figure is a polygon?
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 polygon has 9 sides?
A nine sided shape is a polygon called a nonagon. It has nine straight sides that meet at nine corners. The word nonagon comes from the Latin word “nona”, meaning nine, and “gon”, meaning sides. So it literally means “nine sided shape”.
How many are in the Pentagon?

What do you call a polygon with 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 are the types of pentagons?
Regular polygon.
What is the simplest polygon?
In geometry, a simple polygon /ˈpɒlɪɡɒn/ is a polygon that does not intersect itself and has no holes. That is, it is a flat shape consisting of straight, non-intersecting line segments or “sides” that are joined pairwise to form a single closed path. The number of edges always equals the number of vertices.
What do we call a polygon with 12 sides?
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 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 do you call a polygon with 11 sides?
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 do you call a polygon with 13 sides?
A 13-sided polygon, sometimes also called the triskaidecagon. SEE ALSO: Polygon, Regular Polygon.
Are all polygons regular?
In Euclidean geometry, a regular polygon is a polygon that is equiangular (all angles are equal in measure) and equilateral (all sides have the same length). Regular polygons may be either convex or star.Regular polygon. Set of convex regular n-gons Dual polygon Self-dual Area (with side length, s) Internal angle Internal angle sum.
Are ovals polygons?
The circle and oval are not polygons, which means their area and perimeter are calculated differently.
What is polygon example?
A polygon is a two-dimensional geometric figure that has a finite number of sides. An example of a polygon is a triangle with three sides. A circle is also a plane figure but it is not considered as a polygon, because it is a curved shape and does not have sides or angles.
What is a 100 sided shape called?
In geometry, a hectogon or hecatontagon or 100-gon is a hundred-sided polygon.
What is a 200 sided shape called?
What is the name of a polygon with? # Name of the Polygon + Geometric Drawing 200 sides dihectogon 300 sides trihectogon 400 sides tetrahectogon 500 sides pentahectogon.
What polygon has 4 sides?
Definition: A quadrilateral is a polygon with 4 sides. A diagonal of a quadrilat- eral is a line segment whose end-points are opposite vertices of the quadrilateral.
What do pentagons look like?
A pentagon shape is a flat shape or a flat (two-dimensional) 5-sided geometric shape. In geometry, it is considered as a is a five-sided polygon with five straight sides and five interior angles, which add up to 540°.
How many sides did pentagon have?
five sides Pentagon An equilateral pentagon, i.e. a pentagon whose five sides all have the same length Edges and vertices 5 Internal angle (degrees) 108° (if equiangular, including regular).
Why does the Pentagon have 5 sides?
Some of the information contained within may be outdated and links may not function. Please contact the DOD Webmaster with any questions. Why is the Pentagon, you know, a pentagon? The land the Pentagon was first planned to go on was bordered on five sides by roads, so the architects designed a five-sided building.
Are circles a strong shape?
There are several shapes that are used when strength is important. The arc (think: circle) is the strongest structural shape, and in nature, the sphere is the strongest 3-d shape. The reason being is that stress is distributed equally along the arc instead of concentrating at any one point.
What is the name of the shape that has infinite sides?
apeirogon The regular apeirogon Edges and vertices ∞ Schläfli symbol {∞} Coxeter–Dynkin diagrams Internal angle (degrees) 180°.
What’s the largest sided polygon?

What is a polygon with 8 sides?
Regular octagon Regular octagon Type Regular polygon Edges and vertices 8 Schläfli symbol {8}, t{4} Coxeter–Dynkin diagrams.
What is a polygon with 6 sides?
In geometry, a hexagon (from Greek ἕξ, hex, meaning “six”, and γωνία, gonía, meaning “corner, angle”) is a six-sided polygon or 6-gon. The total of the internal angles of any simple (non-self-intersecting) hexagon is 720°.
Do regular polygons have equal sides?
A polygon is called regular if it has equal sides and angles. Thus, a regular triangle is an equilateral triangle, and a regular quadrilateral is a square.
Can a pyramid have 5 sides?
In geometry, a pentagonal pyramid is a pyramid with a pentagonal base upon which are erected five triangular faces that meet at a point (the vertex). Like any pyramid, it is self-dual. Pentagonal pyramid Faces 5 triangles 1 pentagon Edges 10 Vertices 6 Vertex configuration 5(3 2 .5) (3 5 ).
Is Nonagon a polygon?
In geometry, a nonagon (/ˈnɒnəɡɒn/) or enneagon (/ˈɛniəɡɒn/) is a nine-sided polygon or 9-gon. The name nonagon is a prefix hybrid formation, from Latin (nonus, “ninth” + gonon), used equivalently, attested already in the 16th century in French nonogone and in English from the 17th century.
Is a circle a polygon?
Complete step-by-step answer: A circle is not a polygon. A polygon is a closed figure on a plane formed from a finite number of lines segments connected end-to-end. As a circle is curved, it cannot be formed from line segments, as thus does not fit the conditions needed to be a polygon.
