The sum of the interior angles of an n sided polygon is (n - 2)*180 degrees.
Since n = 15, the answer is 13*180 = 2340 degrees.
As a polygon consists of straight lines that are joined to form a closed chain or circuit, they can be of any shape and have different degrees of angle.
Therefore, each angle would need to be measured and totalled to produce the sum.
