30 degrees

The sum of the external angles of any regular polygon is equal to 360. Therefore, a single exterior angle of an icosagon is 360/20 = 18 degrees.

The interior angles of a regular polygon must be 60 degrees or greater.

The exterior angles of a 6 sided hexagon add up to 360 degrees

For any polygon, regular or otherwise, the sum of exterior angles is always 3600.

That's true if the interior angles are 108 degrees, but a regular polygon cannot have exterior angles of 108 degrees.

The sum of the exterior angles of any polygon is 360 degrees.

If its a regular 9 sided polygon then the exterior angles are 40 degrees.

Even if it's not a regular polygon, the sum of the exterior angles will still total 360 degrees.

A regular polygon will have 360 sides with exterior angles of 181 degrees.

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 sum of the exterior angles of a n-gon is 360 degrees, whatever the vaue of n. If the polygon is regular, these exterior angles have the same measure, so each is 360/n degrees. So a regular pentagon has exterior angles of 360/5 = 72 degrees.

Yes.
