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
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 shape with 7 sides and 7 angles is called a heptagon. A heptagon is a polygon with seven straight sides and seven interior angles. Each interior angle of a regular heptagon measures 128.57 degrees.
