Sum of what aspect of a 20-gon: the length of its sides, its interior angles, its exterior angles, its apothems?
Sum of the angles of a regular polygon = (#sides - 2) * 180. Sum of 20-gon angles = (20-2) * 180 = 3240
The sum of the interior angles add up to 3240 degrees.
The 20 interior angles add up to 3240 degrees
Interior angles: 3240 degrees Exterior angles: 360 degrees
The interior angles add up to 3240 degrees
The 20 interior angles of a regular 20-agon add up to 3240 degrees
The formula is: (20-2)*180 = 3240 degrees which is the total sum of interior angles
3240 total degrees. Each angle is 162 degrees
(22-2)180 (20)180 = 3,600
Exterior angles add up to 360 degrees Interior angles add up to 3240 degrees
Exterior angles add up to 360 degrees Interior angles add up to 3240 degrees
