Interior angles add up to 1440 degrees
Exterior angles add up to 360 degrees
The interior angles of a 17 sided polygon add up to 2700 degrees
It is a regular 20 sided polygon
The 13 interior angles of a 13 sided polygon add up to 1,980 degrees
The sum of the measures of the interior angles of an ( n )-sided polygon can be calculated using the formula ( (n - 2) \times 180 ) degrees. For an 18-sided polygon, this would be ( (18 - 2) \times 180 = 16 \times 180 = 2880 ) degrees. Therefore, the sum of the interior angles of an 18-sided polygon is 2880 degrees.
