#### What is the interior angle of a 12 sided polygon

## What is the sum of the interior angle of a 12 sided polygon?

Using the same methods as for hexagons to the right (I’ll let you do the pictures) So, the sum of the interior angles of a dodecagon is 1800 degrees .

## How do you calculate the size of an interior angle in a regular 12 sided polygon?

[insert carefully drawn regular 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°

## What is the interior angle of a 13 sided polygon?

152.31°

## How do you find the interior angle of an N sided polygon?

Explanation: The sum of the interior angles , in degrees, of a regular polygon is given by the formula 180( n – 2), where n is the number of sides .

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

3240 degrees

## What is the interior angle of a 15 sided polygon?

156°

## 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 a 13 sided shape called?

tridecagon

## What is a 70 sided shape called?

heptacontagon

## What is a 200 sided shape called?

dihectogon

## What do you call a 12 sided shape?

In geometry, a dodecagon or 12 -gon is any twelve- sided polygon .

## What is the sum of interior angles of N sided polygon?

The General Rule

Shape | Sides | Sum of Interior Angles |
---|---|---|
