The sum of interior and exterior angle is 180, thus<span>Interior angle =180−72=108 degrees </span>Let n be the number of sides of the polygon<span><span>(n−2)×180 / n = interior angle =108</span></span><span>72n = 360</span><span> n = 5 sides, hence this is a pentagon.
Sum of the interior angles = 108*5 = 540 degrees.</span>
