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 .
