Interior Angles of a Regular Dodecagon

Hard Geometry Polygons

Consider a regular polygon with n sides. The sum of the interior angles of this polygon is given by the formula:

$$ S = (n - 2) \times 180 $$

Now, let n equal 12, representing a regular dodecagon. Each interior angle of a regular dodecagon can be calculated using the formula:

$$ A = \f\frac{S}{n} $$

Determine whether the measure of each interior angle of this dodecagon is less than, greater than, or equal to 150 degrees.
