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.
360 degrees. The sum of the measures of the exterior angles of any polygon is 360°.
The sum of the interior angles of a four-sided polygon is 360 degrees.
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.
The sum of what of a 92 sided polygon? The lengths of the sides? The exterior angles? The interior angles?
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.
A 9 sided nonagon has 9 interior angles that add up to 1260 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
