Providing that it's a regular polygon then each exterior angle will measure 12 degrees.


What is the formula on how to get the measure of the exterior angle of the regular polygon?

360/number of sides = exterior angle


How do you measure the interior angle of a polygon?

With a protractor or if you know the exterior angle then it's 180 - exterior angle = interior angle


How can you get the measure of an interior angle if you have the measure of the exterior angle of a regular polygon?

It is: 180-exterior angle = interior angle because there are 180 degrees on a straight line


What is the measure of the exterior angle for an 11 sided polygon?

The measure of the exterior angle of a 11-sided polygon = 360⁰/11 = 32 72/99⁰ = 32 8/11⁰

Providing that it is a regular 12 sided polygon then each exterior angle measures 30 degrees


Exterior angle of a 8 sided polygon?

The sum of the exterior angle of any polygon is 360. So divide that by 8 in this case and each exterior angle has measure 360/8 or 45 degrees.


What is the measure of the exterior angle of a regular 9 side polygon?

400 exterior angle = 360/9 = 400


What is the formula for finding the measure of an exterior angle in a regular polygon?

360/number of sides = each exterior angle


What is the exterior angle of a pollygon?

An exterior angle of a polygon is the supplement of the corresponding interior angle. The exterior angle is the angle between an extended sides of the polygon and the next side of the polygon.


The measure of an exterior angle at the vertex of a polygon equals the measure of the adjacent interior angle?

Very rarely.


What is the measure of an exterior angle of a regular 18-sided polygon to the nearest tenth?

Each exterior angle will measure 360/18 = 20.0 degrees


The measure of an interior angle of a regular polygon is 150 degrees Find the number of sides?

AnswerIt is Dodecagon.To find this, you have to first find the exterior angle of the polygon. Since the exterior angle of a polygon is always supplementary to the interior angle, you subtract the measure of the interior angle from 180. 180-150=30. Now You divide 360 by the measure of the exterior angle to get the number of sides of the polygon. 360/30=12. A 12-sided polygon is called a dodecagon


What is the measure of each exterior angle of a regular polygon with 45 sides?

Each exterior angle measures 8 degrees


What is the measure of each exterior angle of a regular 15-sided polygon?

Each exterior angle measures 24 degrees


What is the measure of each exterior angle of regular 12 sided polygon?

Each exterior angle measures 30 degrees


How do you work out the exterior angle?

Measure it. There is no formula for an exterior angle unless you have a regular (or equiangular) polygon. And there is no evidence to suggest that that is the case.
