A 29-sided polygon.
360 ________________________________________________ Sum of Interior Angles of a Polygon = 180 (n-2) Sum of Exterior Angles of a Polygon = 360 The sum of an angle and an exterior angle of a regular polygon is 360
(number of sides -2)*180 = sum of interior angles
It depends on what type of polygon it is and how many angles it has.
The sum of the interior angles of a polygon with n sides is 180(n-2). Here is my explanation about it.http://math4allages.wordpress.com/2009/10/21/angle-sum/
There is no regular polygon with an interior angle of 20o. If the interior angle is 120o then there are six sides and the sum of the angles is 720o.
A 29-sided polygon.
A pentagon
No
The sum of each pair of interior and exterior angles of a polygon is always 180 degrees.
Im stuck on that too :/

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.
