The sum of the exterior angles of any polygon and the extension of its adjacent side is 360 degrees.
If the 20 sided polygon is regular, then each angle is equal so that each one is 360/20 = 18 degrees.

What is the exterior angle of a regular 18 sided polygon?
20 degrees. The exterior angles always add up to 360 degrees.
Each exterior angle of a regular polygon measures 20 degrees how many sides does the polygon have?
The sum of the exterior angles of any polygon is 360 degrees. If each angle is 20 degrees, there must be 360/20 = 18 such angles. 18 angles means 18 sides so it is an 18-sided polygon.
What are the angles of a 20 sided polygon?
The name of a 20 sided polygon is Icosagon.
Each interior angle of a regular polygon measures 162 degrees How many sides does the polygon have?
I believe it may be a 20-sided polygon (a 20-gon). Usually the interior and exterior angles add up to 180. 180 - 162 = 18 So 18 is the exterior angle. Since the exterior angles add up to 360 degrees 360/18 = 20 There you have your answer.
What is the sum of the exterior angles of a 18 sided polygon?
360 degrees, it's the same for every polygon360 degrees is the sum of the angles of any side and the extension of the adjacent side in a polygon.With an 18 sided regular polygon this would be 20 degrees.See the related link for a graphic.
What is the exterior measure of a 20 sided polygon?
The exterior angles add up to 360 degrees
What is the exterior angle of a twenty sided ploygon?
The sum of the exterior angles of a polygon, however many sides it has, is 360 degrees. If the 20 sided polygon is regular, its angles are equal, and each is then 360/20 = 18 degrees.
What is the size of the exterior angle of a 20 sided polygon?
The question can be answered only if the 20-gon is regular - ie all its angles are the same. IF that is the case, then: The sum of the exterior angles of any polygon is 360 degrees. Since there are 20 exterior angles, each of them must be 360/20 = 18 degrees.
What is the exterior angle of a regular 18 sided polygon?
20 degrees. The exterior angles always add up to 360 degrees.
Each exterior angle of a regular polygon measures 20 degrees how many sides does the polygon have?
The sum of the exterior angles of any polygon is 360 degrees. If each angle is 20 degrees, there must be 360/20 = 18 such angles. 18 angles means 18 sides so it is an 18-sided polygon.
What are the angles of a 20 sided polygon?
The name of a 20 sided polygon is Icosagon.
What Is the sum of the angles of an 20 sided polygon?
The interior angles of a 20 sided polygon add up to 3240 degrees
What shape has a exterior angle of 20 degrees?
A regular 18 sided polygon has 18 exterior angles each measuring 20 degrees
Each interior angle of a regular polygon measures 162 degrees How many sides does the polygon have?
I believe it may be a 20-sided polygon (a 20-gon). Usually the interior and exterior angles add up to 180. 180 - 162 = 18 So 18 is the exterior angle. Since the exterior angles add up to 360 degrees 360/18 = 20 There you have your answer.
What is the sum of the interior angle measured by a 20-sided polygon?
162o. Method 1: Sum of interior angles of n-sided polygon = (2n - 4) right angles. In this case n = 20 so total of interior angles is 36 x 90o. Assuming polygon is regular then each interior angle is (36 x 90) divided by 20 = 3240/20 = 162. Method 2: Exterior angles of regular n-sided polygon = 360/n which in this case = 360/20 =18. Straight line is 180o so interior angle = (180 - exterior angle) = 180 - 18 = 162.
What is the sum of interier angles for a twenty sided polygon?
The interior angles of a 20 sided polygon add up to 3240 degrees
What is the sum of the angles of 20 sided polygon?
Sum of interior angles of n-sided polygon = 180n - 360 degrees. When n = 20 this gives 3240o
