WebThere are 180 (N – 2) degrees in a polygon if we add up the measures of every interior angle: Sum of Interior Angles of an N-gon = 180 (N – 2) degrees. For example, a polygon with N = 22 sides has 180 (22 – 2) = 180 (20) = 3600 degrees. That is, the sum of all interior angles in a 22-sided polygon is 3600 degrees. 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. WebSep 6, 2024 · Has 7 interior angles each measuring 128.57°; so ∠ABC = ∠BCD = ∠CDE = ∠DEF = ∠EFG =∠FGA = ∠GAB The sum of all seven … 7 grandfather teachings humility
