The sum of the interior angles of an n-gon are 180*(n-2) degrees. Whether the polygon is regular or not makes no difference.
When n = 15, this is 180*13 = 2340 degrees.
Exterior angles are 360 degrees Interior angles are 1260 degrees
360 degrees * * * * * No, that is the sum of the Exterior angles. The sum of the interior angles is 180*(8 - 2) = 180*6 = 1080 degrees.
The sum of the exterior angles of any polygon is 360 degrees.
The sum of the interior angles add up to 540 degrees. The sum of the exterior angles add up to 360 degrees.
1440 degrees. The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees.
S of interior angles of ANY n-sided polygon is (2n -4) right angles, so 2 x 30 - 4 = 56, 56 x 90 = 5040 degrees
1260 degrees
360 degrees.
The sum of all the interior angles of a regular octagon is 360 degrees.
The sum of the exterior angles cannot be 1980 degrees - it is always 360 degrees.
The sum of the measures of the exterior angles of any polygon, regular or irregular, is always 360 degrees. In a regular polygon with ten sides, each exterior angle measures 360 degrees divided by the number of sides, which in this case is 36 degrees. Therefore, the sum of the measures of the exterior angles of a regular decagon is 10 multiplied by 36 degrees, which equals 360 degrees.
all regular polygons (such as a pentagon) have the sum of their exterior angles = 360 degrees
