A pentagon is a polygon with 5 sides. To find the sum of the interior angles of any polygon, we use the formula (n-2)180, where n represents the number of sides. In this case, n=5, so the sum of the interior angles of a pentagon is (5-2)180 = 3*180 = 540 degrees. Option A (360) is the sum of the interior angles of a quadrilateral (4-sided polygon), which is incorrect for a pentagon. Option C (720) and D (900) are both sums of the interior angles of polygons with more than 5 sides, making them incorrect for a pentagon.
