The internal angles of a regular nonagon (a polygon having 9 sides) are obtuse angles of 140o.
Providing that it is a regular nonagon then each exterior angle measures 40 degrees and each interior angle measures 140 degrees
The formula for finding the interior angle of a regular n-gon is: (n-2)180/n Since we are dealing with a nonagon (9-gon): we plug 9 in for n and get: (9-2)180/9 = 7 x 180 / 9 = 140 So the measure of each interior angle of a nonagon is 140 degrees.
A regular polygon with an exterior angle of40O is a nonagon, and has 9 sides.
Providing that it is a regular polygon then it is a nonagon which has 9 sides
No - each different n-gon (pentagon, septagon, nonagon, etc) has a different angle measurement.
Each angle for a regular nonagon is 140 degrees each.
140 degrees
Providing that it is a regular nonagon then each exterior angle measures 40 degrees and each interior angle measures 140 degrees
The exterior angles of a nonagon add up to 360 degrees.

1260
It is called a Nonagon
1260
The measure of an interior angle of a regular nonagon is 140o. This is found in any polygon by multiplying 2 less than the number of sides by 180o and then dividing the product by the number of sides. A nonagon interior angle is then 7 x 180o/9 = 140o.
