If the 12-sided polygon is 'regular', then each of its exterior angles is 30 degrees.
Whether the polygon is regular or not, all 12 of its exterior angles still add up to
360 degrees, but they may not all be equal.
Providing that it's a regular polygon then each exterior angle will measure 12 degrees.
400 exterior angle = 360/9 = 400
The exterior angle of a 52-sided polygon is 360/52 = 6.92 degrees, approx.
56
180 minus interior angle = exterior angle because there are 180 degrees on a straight line
The largest exterior angle measure is 120o. It is the exterior measure of an equilateral triangle (which is a regular polygon).
360/number of sides = exterior angle
Providing that it's a regular polygon then each exterior angle will measure 12 degrees.
With a protractor or if you know the exterior angle then it's 180 - exterior angle = interior angle
It is: 180-exterior angle = interior angle because there are 180 degrees on a straight line
Providing that it is a regular polygon then each exterior angle will measure 12 degrees
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
400 exterior angle = 360/9 = 400
360/number of sides = each exterior angle
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
Very rarely.
