The sum of the exterior angles of a polygon, however many sides it has, is 360 degrees. If the 20 sided polygon is regular, its angles are equal, and each is then 360/20 = 18 degrees.
Sum of exterior angles of any sided polygon is 360 so sum of exterior angle of 6 sided polygon (hexagon) is 360
1260 degrees
The sum of the exterior angles of any polygon, including a 27 sided one, is 360 degrees.
1800 degrees in total
360 degrees
360 degrees
The exterior angles of a REGULAR 15-gon are 204o, so the sum would be 3060o. This remains true for non-regular 15-gons as well (the exterior angle sum, not the exterior angles).
The 8 exterior angles add up to 360 degrees
The sum of the exterior angle of any polygon is 360. So divide that by 8 in this case and each exterior angle has measure 360/8 or 45 degrees.
Sum of exterior angles = 360 degrees Sum of interior angles = 1980 degrees
Remember the two equations. Exterior angle = 360 / no. of sides. Interior angle = 180 - exterior angle. So for 102 sided polygon. exterior angle = 360/102 = 3.5294... Interior angle = 180 - 3.5294... = 176.4706.... Hence sum of the 102 sided polygon's angles is 102 X 176.4706 = 18,000 degrees. ( to nearest degree).
