If the sum of the interior angles of a regular polygon measures up to 1440 degrees, how many sides does the polygon have?

We know that the sum of an exterior angle and an interior angle of a polygon = 180⁰.

We also know that sum of all the exterior angles of a polygon = 360⁰.

The question states that the sum of all interior angles of the given polygon = 1440⁰.

Therefore, sum of all the interior and exterior angles of the polygon = 1440 + 360 = 1800

If there are ‘n’ sides to this polygon, then the sum of all the exterior and interior angles = 180 * n = 1800

Therefore, n = 10.
