360/9 = 40 degrees
The exterior angles of a nonagon add up to 360 degrees.
The sum of all the exterior angles of a nonagon is 360 degrees. Any specific exterior angle can have any value between 0 and 360 degrees (except 180) subject the their sum being 360.
The sum of the exterior angles of any polygon is 360 degrees. this is true whether the figure is regular or irregular, and irrespective of how many sides/vertices it has. For a regular nonagon, the 9 equal external angles sum to 360 degrees and so each measures 360/9 = 40 degrees.
The sum of the exterior angles of a polygon, with any number of sides (or vertices) is always 360 degrees.
An interior angle of a regular octagon is 45 degrees. The exterior angles measure 315 degrees.
All exterior angles of any polygon sum to 360 deg. If there are 9 angles then each angle is 40 degrees.
As for all polygons the exterior angles add up to 360 degrees
Exterior angles 360 degrees Interior angles 1260 degrees
9
The exterior angle would have to be greater than 180 degrees. If you mean interior angle then a regular nonagon (9 sided) will have angles of 140 degrees.
The internal angles of a regular nonagon are 140o, so the exterior angles must be 220o (360o-140o).
The sum of the interior angles of a polygon is 2n-4 Right Angles For a nonagon (2x9)-4 RAs = 14x90°=1260° To find the interior angle of a regular nonagon, divide this by 9 which gives 140° To find the exterior angle, subtract this from 180 and you get 40°. The sum of the exterior angles of a polygon is 360°, so for a regular polygon you can also divide this by the number of sides, which in this case also gives: 360° ÷ 9 = 40°
Since all exterior angles add up to 360, 40 degrees
The exterior angles of a nonagon add up to 360 degrees.
The formula for an exterior angle is 180-(180/n)(n-2) where n is the number of sides. For a nonagon the number of sides is 9. Plugging this into the equation gives: 180-(180/9)(9-2) =180-(20)(7) =40 So the exterior angles of a regular nonagon will measure 40 degrees.
If it's a regular 9 sided nonagon then each exterior angle measures 40 degrees because the exterior angles of any polygon add up to 360 degrees and 360/9 = 40 degrees If it was an irregular nonagon then the exterior angles would vary but they still would add up to 360 degrees
The sum of all the exterior angles of a nonagon is 360 degrees. Any specific exterior angle can have any value between 0 and 360 degrees (except 180) subject the their sum being 360.
