# What is a polygon shape?

## What is a polygon shape?

A polygon is a flat, two-dimensional (2D) shape with straight sides that is fully closed (all the sides are joined up). The sides must be straight. Polygons may have any number of sides. A polygon. A shape with curved sides is not a polygon.

## What is polygon example?

A polygon is any 2-dimensional shape formed with straight lines. Triangles, quadrilaterals, pentagons, and hexagons are all examples of polygons. For example, a triangle has three sides, and a quadrilateral has four sides.

## Is a polygon equal to 180?

A special rule exists for regular polygons: because they are equiangular, the exterior angles are also congruent, so the measure of any given exterior angle is 360/n degrees. As a result, the interior angles of a regular polygon are all equal to 180 degrees minus the measure of the exterior angle(s).

## How many sides is a polygon?

Other Types of Polygons

Polygon Number of Sides
Pentagon 5
Hexagon 6
Heptagon 7

## What is a polygon class 8?

A polygon is a two-dimensional enclosed figure made by joining 3 or more straight lines. A polygon having equal sides of equal lengths are called regular polygons. A regular polygon is a polygon that is equiangular i.e. All the angles are equal in measure and equilateral i.e. all sides have the same length.

## What is a polygon with 4 sides?

Definition: A quadrilateral is a polygon with 4 sides. Definition: A parallelogram is a quadrilateral where both pairs of opposite sides are parallel.

## What is a polygon for kids?

Any closed two-dimensional shape with three or more sides is called a polygon. Polygons can be regular or irregular. The sides and angles of a regular polygon are all equal. An irregular polygon has at least two sides or two angles that are different.

## What is meant polygon?

A polygon is a closed shape with straight sides. Rectangles, triangles, hexagons, and octagons are all examples of polygons. The word polygon comes from the Greeks, like most terms in geometry, which they invented. It simply means many (poly) angles (gon).

## Are all polygons 360 degrees?

Exterior angles of a polygon have several unique properties. The sum of exterior angles in a polygon is always equal to 360 degrees. Therefore, for all equiangular polygons, the measure of one exterior angle is equal to 360 divided by the number of sides in the polygon. an exterior angle.

## What is the polygon whose sum of the interior angles is 1 080?

octagon
The polygon with an interior angle sum of 1080° is an octagon, or a polygon with 8 sides.

## What is not a polygon?

A polygon is a closed plane figure with three or more sides that are all straight. A circle is not a polygon as it does not have straight sides. …

## What is a polygon Class 6?

A polygon is a closed figure formed of three or more line segments. Examples of polygons are triangle, quadrilateral, pentagon and. hexagon.

## What is a polygon in maths?

In Mathematics, a polygon is a closed two-dimensional shape having straight line segments. It is not a three-dimensional shape. A polygon does not have any curved surface.

## Is a polygon a three-dimensional shape?

It is not a three-dimensional shape. A polygon does not have any curved surface. A polygon should have at least three sides. Each side of the line segment must intersect with another line segment only at its endpoint. Based on the number of sides of a polygon, we can easily identify the polygon shape.

## How many exterior angles does a polygon have?

The first is called the exterior angle, and it is the measurement between the shape and each line segment when you stretch it out past the shape. However many sides a polygon has is the same number of exterior angles it has. So, a pentagon with five sides has five exterior angles.

## What is an example of a regular polygon with 8 equal sides?

A stop sign is an example of a regular polygon with eight equal sides. No matter which way you’re looking at a regular polygon, you wouldn’t be able to tell which way is up because the angles and sides are all the same.
