360/18 = 20 sides
Providing that it's a regular polygon then each exterior angle will measure 12 degrees.
60 degrees
5 sides and it is a regular pentagon
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.
It is best described as a regular 10 sided polygon or as a regular decagon.
A regular polygon will have 360 sides with exterior angles of 181 degrees.
The sum of the exterior angles of a polygon = 360360 / 36 = 10 degrees
Providing that it's a regular polygon then each exterior angle will measure 12 degrees.
60 degrees
5 sides and it is a regular pentagon
There can be no such polygon. The sum of the exterior angles of ANY polygon is 360 degrees. If it is a regular polygon, then the number of angles MUST divide 360 degrees. Since 18.95 does not divide 360, there cannot be such a polygon. If the exterior angle was 18.94737... degrees, it would be a 19-sided polygon.
The measure of 1 exterior angle of a regular 8-sided polygon is equivalent to 45 degrees. Hope I helped! :)
90 degrees. Exterior angle of any regular n-sided polygon is 360/n degrees
Providing that it is a regular polygon then each exterior angle will measure 12 degrees
