The interior angles of an 11 sided polygon add up to 1620 degrees
360 degrees
The sum of the interior angles of a n-sided polygon is (n-2)*180 degrees. So for 13 sides, the sum is 11*180 = 1980 degrees.
(11-2)*180 = 1620 degrees
the 11 sided polygon is undecagon
The name of a 11 sided polygon is Hendecagon.
The interior angles of an 11 sided polygon add up to 1620 degrees

The sum of the interior angles of a n-sided polygon is (n-2)*180 degrees. So for 13 sides, the sum is 11*180 = 1980 degrees.
Sum of exterior angles of any sided polygon is 360 so sum of exterior angle of 6 sided polygon (hexagon) is 360
(11-2)*180 = 1620 degrees
The name of a 21 sided polygon is Icosihenagon.
The name of a 16 sided polygon is Hexadecagon.
The sum of the interior angles of a four-sided polygon is 360 degrees.
the 11 sided polygon is undecagon
The sum of the exterior angles of any n-sided regular polygon, including a seven-sided polygon, is 360 degrees.
