For a seven-sided polygon, what is the sum of interior angles?

Explanation:
The sum of interior angles in a polygon with n sides is (n − 2) × 180 degrees. For a seven‑sided polygon, plug in n = 7: (7 − 2) × 180 = 5 × 180 = 900 degrees. So the interior angles add up to 900 degrees. The other numbers correspond to polygons with fewer sides (e.g., 360 for a quadrilateral, 540 for a pentagon, 720 for a hexagon).
