If it has n sides, then (n-2)*180 = 1440
so n-2 = 1440/180 = 8
and therefore, n = 10
It is a decagon.
Improved Answer:-A 6 sided polygon is an hexagon and its 6 interior angles add up to 720 degrees
It is an hexagon which is a 6 sided polygon with 6 interior angles that add up to 720 degrees.
A polygon with 10 sides is called decagon and the sum of the interior angles is 1440 degrees. (10-2)180=1440
Quindecagon or pentadecagona 15 sided pollygon is called a Pentadecagon, it has interior angles of 156 degrees each
In a polygon there are no such angles.
A 13 sided polygon also called a triskaidecagon or tridecaogn has a total 1980 degrees for its interior angles.
A 6 sided polygon is called a Hexagon. The sum of the interior angles or a regular hexagon is 720 degrees.
A triangle
Improved Answer:-A 6 sided polygon is an hexagon and its 6 interior angles add up to 720 degrees
If all of its interior angles are equal then it is a regular polygon
It has 9 sides and is called a nonagon
It is an hexagon which is a 6 sided polygon with 6 interior angles that add up to 720 degrees.
A polygon with 10 sides is called decagon and the sum of the interior angles is 1440 degrees. (10-2)180=1440
If you mean an 11 sided polygon then its 11 interior angles add up to 1620 degrees
The inside angles of a polygon are called "interior angles." The sum of the interior angles of a polygon can be calculated using the formula ( (n - 2) \times 180^\circ ), where ( n ) is the number of sides in the polygon. Each individual interior angle can be found by dividing the total sum by the number of angles (or sides) if the polygon is regular.
Quindecagon or pentadecagona 15 sided pollygon is called a Pentadecagon, it has interior angles of 156 degrees each
In a polygon there are no such angles.
