The interior angles of a 15 sided polygon add up to 2340 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.
The 13 interior angles of a 13 sided polygon add up to 1,980 degrees
The sum of the three INTERIOR angles is 180 degrees. And a 3-sided polygon is often referred to as a 'Triangle'.
The question has been asked "What is the angle sum of a thirteen sided polygon?" The answer to this question is 1980 degrees. The sum of the interior angles of a polygon of n sides = 180(n - 2)
