#### What is the sum of the measures of the interior angles of a 12-gon?

## How do you find the interior angle of a 12 sided polygon?

Once you know the sum, you can divide that by 12 to get the measure of each interior angle : 1800°/ 12 = 150°

## What is the sum of the measures of the interior angles of a 13 sided polygon?

Question 130236: What is the sum of the measures of the interior anles of a convex 13 -gon? There is a formula the sum of the measures of the interior angles of a convex n-gon is (n-2)180 degrees. For a triangle, n=3, so it’s (1)180=180 degrees.

## What is the sum of the measure of the interior angles of a 14 Gon?

The sum of the interior angles of a 14-gon = (14-2)*180 = 2160 degrees .

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

1800 degrees

## 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 15 Gon?

Each triangle has an angle sum of 180 degrees , so the sum of the interior angles of the 15-gon must be 13 × 180 = 2340 degrees . Since the 15-gon is regular, this total is shared equally among the 15 interior angles. Each interior angle must have a measure of 2340 ÷ 15 = 156 degrees . an octagon we can draw 5 diagonals.

## What is a 70 sided shape called?

heptacontagon

## 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 sum of the interior angles of a 20 sided polygon?

When you divide a polygon into triangles, the number of triangles is always 2 less than the number of sides . This means that all of the interior angles of any 20 – sided polygon add up to 3240°.

## 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 sum of the interior angles of a Heptagon?

900°

## What is the sum of the measures of the interior angles of a regular 16 Gon?

Each angle of a regular hexadecagon is 157.5 degrees , and the total angle measure of any hexadecagon is 2520 degrees .

## What is the sum of the interior angles of a regular polygon with 7 sides?
