What is the sum of the interior angles of a dodecagon (12-sided polygon)?
The sum of the interior angles of any polygon can be calculated using the formula:

Sum of interior angles = (n - 2) * 180°

where n is the number of sides of the polygon.

For a dodecagon (12-sided polygon), we have:

Sum of interior angles = (12 - 2) * 180°
                        = 10 * 180°
                        = 1800°

So, the sum of the interior angles of a dodecagon is 1800 degrees.
