Answer:

The sum of the exterior angles of any polygon always equals 360 degrees. Let's prove this for a polygon with n sides:

1. Start with a polygon with n sides.

2. Extend each side of the polygon to form its corresponding exterior angle.

3. Each interior angle of the polygon pairs with an exterior angle to form a straight line (180 degrees).

4. Since there are n interior angles in the polygon, there are also n exterior angles.

5. The sum of all the interior angles of a polygon with n sides is given by the formula: (n - 2) * 180 degrees. This is a well-known result in geometry.

6. Therefore, the sum of all the exterior angles must be equal to 360 degrees because each interior-exterior angle pair forms a straight line (180 degrees), and there are n such pairs.

So, in general, for any polygon with n sides, the sum of its exterior angles is always 360 degrees.
