The exterior angle is defined as the supplement to the interior angle. Intuitively it should be the whole of the exterior part of the angle - that is, 360 deg minus the interior angle.
As a result of this definition, the question of reflex angles does not arise. Also, the sum of all the exterior angles of a polygon is 360 deg so if each one is 10 degrees, there must be 360/10 = 36 angles and so 36 sides.
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.
The sum of the exterior angles of any n-sided regular polygon, including a seven-sided polygon, is 360 degrees.
If those are exterior angles, the exterior angles of any polygon add up to 360. That would be 20 sides.
5 sides and it is a regular pentagon
The exterior angles of any polygon always add up to 360 degrees
A regular polygon with exterior angles of 30 degrees has: 360/30 = 12 sides
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.
Even if it's not a regular polygon, the sum of the exterior angles will still total 360 degrees.
If its a regular 9 sided polygon then the exterior angles are 40 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.
A regular polygon will have 360 sides with exterior angles of 181 degrees.
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.
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.
