How many sides does a pentagon have?

In geometry, a pentagon is any five-sided polygon or 5-gon. The sum of the internal angles in a simple pentagon is 540°. A pentagon may be simple or self-intersecting. A self-intersecting regular pentagon is called a pentagram.

Is a pentagon has 6 sides?

The universal fact is that a pentagon has five sides, five corners, and five interior angles. It is a flat and enclosed shape, meaning no sides are curved and joined. If these sides and angles are equal, it is known as a regular pentagon.

What are the 7 polygons?

Does a pentagon have 5 equal sides?

An equilateral pentagon is a polygon with five sides of equal length.

How many sides does 1 pentagon have?

A pentagon is any polygon that has five sides and five angles. The root of the word pentagon is “penta” which comes from the Greek word for five. “Gon” comes from the Greek word for angle. So, if you put the two words together, you get “five angles,” which corresponds to how many angles are in the shape.

How many sides does a pentagon have?

How many sides is a hexagon?

Properties of Hexagon

It is two-dimensional. It has six sides, six edges and six vertices. The sum of the interior angles is 720 degrees.

What do you call a polygon with 99 sides?

What is a 99 sided shape called? In geometry, an enneacontagon or enenecontagon or 90-gon is a ninety-sided polygon. Thus, the 99 sided shape is called nonacontakainonagon or enneacontanonagon. Here, enneaconta is the prefix for the number of sides numbered from 90 to 99.

What is a 7 sided shape called?

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 do you call a 1000 sided shape?

In geometry, a chiliagon (/ˈkɪliəɡɒn/) or 1000-gon is a polygon with 1,000 sides. Philosophers commonly refer to chiliagons to illustrate ideas about the nature and workings of thought, meaning, and mental representation.

What is a shape with 1 million sides called?

A megagon or 1,000,000-gon is a polygon with one million sides (mega-, from the Greek μέγας, meaning "great", being a unit prefix denoting a factor of one million). Regular megagon. A regular megagon. Type. Regular polygon.

What is a polygon with 12 sides called?

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's a 9 sided shape?

A 9-sided figure is called a nonagon in geometry. It is also called enneagon or 9-gon.

Do triangles have 4 sides?

The triangle has three (3) sides. The triangle is a polygon that contains three sides and three inner angles and three vertices.

What does a pentagon 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°. Pentagons can be simple or self-intersecting.

What is a 8 sided polygon?

In simple words, the octagon is an 8-sided polygon, also called 8-gon, in a two-dimensional plane. A regular octagon will have all its sides equal in length. Each interior angle of a regular octagon is equal to 135°. Therefore, the measure of exterior angle becomes 180° – 135° = 45°.

What is a 100 sided shape called?

A 100-sided polygon is called a hectogon.

What is 8 sided shape called?

An octagon is a shape with 8 sides and 8 angles. A trapezoid is a quadrilateral with one set of parallel sides.

What is a 10000 sided shape?

In geometry, a myriagon or 10000-gon is a polygon with 10,000 sides. Several philosophers have used the regular myriagon to illustrate issues regarding thought.

What is a 101 sided shape called?

Also, 101-sided is "hectakaihenagon" (as I understand from your rules) or "hectahenagon"? @beary605 I think nona- is wrong. That would be from latin and the others, hepta-, hexa- are from greek.
