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. WebOct 3, 2024 · For example, to find out the sum of the interior angles of a hexagon, you would calculate: So, the sum of the interior angles of a hexagon is 720 degrees. Method …

Weba 7 sided polygon 7 (5/7) π = 900°/7 = 128.57° (2/7) π = 360°/7 = 51.43° octagon an 8 sided polygon 8 (6/8) π = 135° (2/8) π = 45° nonagon a 9 sided polygon 9 (7/9) π = 140° (2/9) π = 40° decagon a 10 sided polygon … WebJan 12, 2024 · The interior angles are each 140°. You can verify this because 1260° ÷ 9 (angles) = 140°. The central angle is 40° (which you can calculate by dividing 360° by 9 ). This means you can construct a regular nonagon with 7 isosceles triangles with two angles of 70° and one angle of 40°. Irregular nonagon 7 glenora court frankston
