## What is the measure of one interior angle in a regular 20 Gon?

The measure of each interior angle of a regular 20-gon is 162°. Since our polygon is regular, and it has 20 sides, we can use our formula for the

## What is the measure of one interior angle of a regular 21 Gon?

The interior angle of a regular 21 – gon is around 162.86∘ .

## What is the formula for interior angles?

An interior angle is located within the boundary of a polygon. The sum of all of the interior angles can be found using the formula S = (n – 2)*180. It is also possible to calculate the measure of each angle if the polygon is regular by dividing the sum by the number of sides.

## What is the sum of the interior angles of a 25 sided polygon?

The sum of any pentacontagon’s interior angles is 8640 degrees .

## What is the measure of one interior angle of a regular 14 Gon?

The measure of each interior angle of a regular polygon with 14 sides is about 154.3.

## What is the measure of one interior angle of a regular 18 Gon?

A polygon with 18 sides has 18 interior angles. Therefore, to find the measure of one of these angles, divide the sum by 18. Answer: Each angle is 160 degrees .

## What is the sum of the interior angles of a 17 sided polygon?

The sum of the interior angles of a 17 – sided convex polygon is 2700°, and the sum of the exterior angles is 360°.

## What is the measure of one interior angles in a regular 9 Gon?

To find the value of an internal angle within this polygon , we can just multiply the number of triangles by 180 ° , then divide by the number of internal angles, which is nine. Excellent! So the interior angle of a 9 -sided polygon is 140 ° .

## What is the measure of interior angles of a regular polygon?

(n-2)x 180 degrees : The formula for finding the sum of all angles in a polygon ( REGULAR ). Here “n” represents the number of sides of the polygon .

## What is the measure of one interior angle in a regular pentagon?

The General Rule

If it is a Regular Polygon (all sides are equal, all angles are equal) | ||

Shape | Sides | Each Angle |
---|---|---|

Triangle | 3 | 60° |

Quadrilateral | 4 | 90° |

Pentagon | 5 | 108° |

## How many sides does a polygon have with an interior angle of 135?

eight sides

## How many sides does a polygon have with an interior angle of 108?

Each interior angle of the polygon is 108 degrees, so each exterior angle of the polygon is 180-108 = 72 degrees. So the number of sides is 360/72 = 5.

## What is the sum of the interior angles of a 21 sided polygon?

In geometry, an icosagon or 20-gon is a twenty-sided polygon. The sum of any icosagon’s interior angles is 3240 degrees . Icosagon.
