Any value between 0 and 360 degrees (excluding 180 degrees).
A nonagon or a polygon with 9 sides.
An angle is a measurement of degrees and as such it is not a polygon.
Providing that it is a regular polygon then it is a nonagon which has 9 sides
140 degrees
A polygon with 9 sides is called a nonagon. A nonagon is a closed shape with nine straight sides and nine angles. It is also known as an enneagon. Each interior angle of a regular nonagon measures 140 degrees.
A regular polygon with an exterior angle of40O is a nonagon, and has 9 sides.
The internal angles of a regular nonagon (a polygon having 9 sides) are obtuse angles of 140o.
If each exterior angle of a regular polygon measures 40 degrees, the polygon is a nonagon (9-sided polygon).
If the measure of an interior angle of a regular polygon is 140o, the polygon is a nonagon (sometimes called an ennagon) having 9 sides.
A irregular nonagon is a polygon that is not a regular polygon.
360/9 = 40 degrees
The name for this polygon is a nonagon,
