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
The total of the interior angles of any n-sided polygon, regular or otherwise, is (2n - 4 right angles) or ((180 times n) minus 360) degrees.
The interior angles of an 11 sided polygon add up to 1620 degrees
A 10 sided decagon polygon has 10 interior angles that add up to 1440 degrees.
It is a regular 9 sided polygon whose 9 interior angles add up to 1260 degrees
If the 12-sided polygon is 'regular', then each of its exterior angles is 30 degrees. Whether the polygon is regular or not, all 12 of its exterior angles still add up to 360 degrees, but they may not all be equal.
The interior angles of a 7 sided polygon add up to 900 degrees
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
assuming it is a regular polygon: the total exterior angles of any regular polygon add up to 360° therefore 360/15=24°
The interior angles of a 20 sided polygon add up to 3240 degrees
The exterior angles of a 14 sided polygon add up to 360 degrees
The interior angles of a 16 sided polygon add up to 2520 degrees If it's a regular polygon then each interior angle measures 157.5 degrees
The total of the interior angles of any n-sided polygon, regular or otherwise, is (2n - 4 right angles) or ((180 times n) minus 360) degrees.
A 10 sided decagon polygon has 10 interior angles that add up to 1440 degrees.
The interior angles of an 11 sided polygon add up to 1620 degrees
