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.
Sum of interior angles of n-sided polygon = 180n - 360 degrees. When n = 20 this gives 3240o
Sum of exterior angles = 360 degrees Sum of interior angles = 1440 degrees
360 degrees
The sum of the exterior angles is always 360 degrees.
The sum of the exterior angles of any polygon, including a 27 sided one, is 360 degrees.
The sum of the interior angles of a four-sided polygon is 360 degrees.
The sum of what of a 92 sided polygon? The lengths of the sides? The exterior angles? The interior angles?
To find the sum of the interior angels of the formula (n-2)*180 is used. The 'n' represents the number of sides. The sum of he interior angles of a nine sided polygon would be (9-2)*180=1260.
Sum of exterior angles of any sided polygon is 360 so sum of exterior angle of 6 sided polygon (hexagon) is 360
The sum of the exterior angles of any n-sided regular polygon, including a seven-sided polygon, is 360 degrees.
There is no such thing as a 2-sided polygon.
The sum of the interior angles of a 12 sided polygon add up to 1800 degrees.
The sum of the exterior angles of any polygon is 360 degrees
The sum of the exterior angles of ANY polygon is 360 degrees.
The sum of the interior angles of a polygon with n sides is 180o × (n - 2), consequently the sum of the interior angles of a 28-sided polygon is 4680o (180o × 26).
The interior angles of a 20 sided polygon add up to 3240 degrees
The interior angles of a 19 sided polygon add up to 3060 degrees
