#### What is the measure of an interior angle in a regular dodecagon?

## What is the measure of an angle in a regular dodecagon?

The internal angle at each vertex of a regular dodecagon is 150°.

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

In order to find the value of the interior angle of a regular polygon , the equation is (n−2)180∘n where n is the number of sides of the regular polygon .

## What is the size of an interior angle of a regular 20 sided polygon?

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 sum of the measures of the interior angles of a dodecagon explain your answer?

To find the sum of the interior angles of a dodecagon, divide it up into triangles. and we get ten triangles. Because the sum of the angles of each triangle is 180 degrees , multiply 10 into 180 and we get 1800 degrees . So, the sum of the interior angles of a dodecagon is 1800 degrees .

## What is the measure of an interior angle of a regular octagon?

The General Rule

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

Octagon | 8 | 135° |

Nonagon | 9 | 140° |

Any Polygon | n | (n−2) × 180° / n |

## What is the measure of the interior angles of a pentagon?

108°

## 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.

## How do you find the measure of an interior angle?

The formula for calculating the size of an interior angle is: interior angle of a polygon = sum of interior angles ÷ number of sides. The sum of exterior angles of a polygon is 360°. The formula for calculating the size of an exterior angle is: exterior angle of a polygon = 360 ÷ number of sides.

## What is the measure of an interior angle of a regular decagon?

All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the angles, we know that the sum of all the angles is 1440 degrees (from above) And there are ten angles So, the measure of the angle of a regular decagon is 144 degrees.

## What is the measure of an interior angle of a regular polygon with 24 sides?

In geometry, an icositetragon (or icosikaitetragon) or 24- gon is a twenty-four-sided polygon. The sum of any icositetragon’s interior angles is 3960 degrees .

## 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 a 21 sided polygon called?

icosikaihenagon

## What is the sum of the measure of the interior angle of a dodecagon?

To find the measure of the angles, we know that the sum of all the angles is 1800 degrees (from above) And there are twelve angles So, the measure of the interior angle of a regular dodecagon is 150 degrees .

## What is the sum of interior angles of a dodecagon?

1800°

## How do you find the sum of the interior angles of a dodecagon?

The interior angles of a dodecagon are a bit harder. You can use this generic formula to find the sum of the interior angles for an n-sided polygon (regular or irregular): Sum of interior angles = (n-2) x 180° Sum of interior angles = 10 x 180° = 1800°
