**What Polygon Has 5 Sides? A pentagon is a five-sided polygon. A regular pentagon has 5 equal edges and 5 equal angles.**

**What polygon has 5 sides and 5 angles? **A pentagon is a shape with 5 sides and 5 angles. An octagon is a shape with 8 sides and 8 angles.

**What is a pentagon with 5 sides? **In geometry, a pentagon (from the Greek πέντε pente meaning five and γωνία gonia meaning angle) 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 (or star pentagon) is called a pentagram.

## What polygon that has 6 sides?

In geometry, a hexagon can be defined as a polygon with six sides. The two-dimensional shape has 6 sides, 6 vertices and 6 angles.

## Are all 5 sided shapes pentagons?

All pentagons (regular and irregular) are five-sided shapes, with five interior angles and five exterior angles.

## What is a 5 sided pyramid called?

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.

## Is a pentagon A polygon yes or no?

A pentagon is a polygon with five sides and five angles and can be either a regular or irregular polygon, depending on the measurements of its sides and angles.

## Is a star a polygon?

By this definition, a star can also be considered as a polygon as it is made up of several line segments known as sides of edges. These edges or sides are connected end to end with each other. A regular polygon is a type of polygon in which all sides are of the same length and the angles are also of the same measure.

## Is a pentagon have?

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 is a 7 sided polygon 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.

## Which polygon has 9 sides?

A nine-sided shape is a polygon called a nonagon. It has nine straight sides that meet at nine corners, or vertices. The word “nonagon” comes from the Latin word “nona”, meaning nine, and “gon”, meaning sides.

## Which 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 2D shape has 5 sides?

A pentagon is a flat 2D shape that has five sides and five vertices. The word “pentagon” comes from the Greek word “pentagonos”, which means “five-angled”. A regular pentagon has five internal angles that form corners.

## What is a 99 sided shape called?

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.

## How many sides does an octagon?

An octagon is a polygon made up of 8 sides. It has eight angles. Octagon = Octa + gon where octa means eight and gon means sides. There are 20 diagonals in an octagon as shown below.

## What polygon has 5 vertices and 3 sides?

In the polygon there are as many vertices as there are sides. The triangle has 3 sides and 3 vertices. The quadrilateral has 4 sides and 4 vertices. The pentagon has 5 sides and 5 vertices.

## Can a polyhedron have 5 faces?

In geometry, a pentahedron (plural: pentahedra) is a polyhedron with five faces or sides. There are no face-transitive polyhedra with five sides and there are two distinct topological types. With regular polygon faces, the two topological forms are the square pyramid and triangular prism.

## Whats a 3D pentagon called?

In geometry, the pentagonal prism is a prism with a pentagonal base.

## What is a shape with 5 vertices?

A pentagon has five straight sides and five vertices (corners). It has five angles inside it that add up to 540°.

## Is a rhombus a polygon?

A rhombus is not a regular polygon.
