WebDec 24, 2015 · The formula for calculating the sum of the interior angles of a regular polygon is: (n - 2) × 180°. Where n is number of sides. sum of angles = (n - 2) × 180. … WebJan 26, 2024 · This formula allows you to mathematically divide any polygon into its minimum number of triangles. Since every triangle has interior angles measuring 180°, multiplying the number of dividing triangles times 180° gives you the sum of the interior angles. S= (n-2)\times 180° S = (n − 2) × 180°. S = sum of interior angles.
