How many sides does a regular polygon have if its exterior angle is 9 degrees?
How many sides does a regular polygon have if its exterior angle is 9 degrees?
Since the angle measure given iin the questions s 40o , take 360o40o = 9. Meaning there are 9 exterior angles and therefore 9 sides to the polygon.
What polygon has an interior angle of 9 degrees?
Nonagon
The General Rule
| Shape | Sides | Sum of Interior Angles |
|---|---|---|
| Hexagon | 6 | 720° |
| Heptagon (or Septagon) | 7 | 900° |
| Octagon | 8 | 1080° |
| Nonagon | 9 | 1260° |
What polygon has an exterior angle of 9?
nonagon
A nonagon has 9 exterior angles. The sum of angles of the exterior angles of a nonagon is 360°.
How many sides does a regular polygon have if the interior angle of a regular polygon is 162 degrees?
20
Summary: The number of sides of a regular polygon, if each of its interior angles is 162° is 20.
How many sides does a regular polygon have if the exterior angle is 4?
Each exterior angle will be 180 – 90 = 90 degrees. We know the sum of exterior angles is 360 degrees. Therefore, the regular polygon has 4 sides.
What is a 9 sided figure?
A nine sided shape is a polygon called a nonagon. It has nine straight sides that meet at nine corners. The word nonagon comes from the Latin word “nona”, meaning nine, and “gon”, meaning sides. So it literally means “nine sided shape”.

How many sides does a regular polygon have if its exterior angles are 30?
As it is a regular polygon, all exterior angles are equal and are 30o . Hence number of sides of the polygon is 360o30o=12 .
