A nonagon is a polygon that has 9 sides and 9 angles
A nonagon is a 9 sided polygon having 9 interior angles
If its a regular 9 sided polygon then the exterior angles are 40 degrees.
It is a nonagon
The number of angles on a polygon is the same number of sides the shape has.
The number of sides of an n-sided polygon is also the number of angles of that polygon. Nonagons have 9 sides, so 9 angles.
(n-2)*180 = sum of interior angles of any polygon where n = number of sides. (9-2)*180 = 1260 degrees.
its called a nonagon.
It is a regular 9 sided polygon whose 9 interior angles add up to 1260 degrees
It is a nonagon which is a polygon that has 9 sides
Total sum of interior angles of a polygon of n sides is found by the equation: S = 180(n-2) For n = 9, S is 1260. Divide 1260 by 9 to get (for regular nonagon): =140
Its 9 because 360 divided by 40 = 9
A polygon has the same number of sides as angles. And, this is always so, not just usually.
A polygon having 30 degree exterior angles is a dodecagon having 12 sides.
If this 9 sided polygon is a regular polygon, then the sum of its angles is:(n - 2)180 degrees = (9 - 2)180 degrees = 7 x 180 degrees = 1,260 degrees.
A 9-gon is a polygon with nine sides and nine angles
Suppose the polygon has n sides. The polygon is regular => each of its exterior angles is equal.The sum of all n angles = 360 deg so each angle is 360/n deg Therefore 360/n = 40 => n = 9 sides. Then perimeter = 9 * length of one side = 63 ft. So each side is 63/9 = 7 ft.
do you mean Nonagon. It is a nine sided polygon, edges and vertices - 9, internal angles 140o
The internal angles of a regular nonagon (a polygon having 9 sides) are obtuse angles of 140o.
The total interior angles add up to 1260 degrees.
The interior angles of a 9 sided polygon add up to 1260 degrees
The exterior angles of any polygon add up to 360. They are 9 degrees each.
