The sum of the measures of the interior angles of a polygon can be calculated using the formula: (n – 2) × 180°, where n is the number of sides of the polygon.
For a 14-sided polygon (also known as a tetradecagon), we can substitute 14 for n in the formula:
- (14 – 2) × 180° = 12 × 180°
- 12 × 180° = 2160°
Therefore, the sum of the measures of the interior angles of a 14-sided polygon is 2160 degrees.
