The interior angles of a 14 sided polygon add up to 2160 degrees
The sum of the interior angles of a convex polygon with n sides is given by (n-2)x180o. So for a 40 sided polygon n=40; thus (40-2)x180o = 38x180o = 6840o.
the interior angle of a 7 sided regular polygon is 128.57 degrees

The method of finding the sum of the interior angles of a polygon is by multiplying the (number of sides)-2 by 180, so the sum of the interior angle measures in a 25-sided polygon would be 23*180, or 4140 degrees.
sum of interior angles of EVERY n-sided polygon is 180n - 360 degrees. When n = 15 sum is 2340 degrees.
196 x 90 = 17640o
The exterior angles of any polygon add up to 360 degrees
Sum of exterior angles = 360 degrees Sum of interior angles = 1980 degrees
