How many diagonals does an 11 gon have
WebEach interior angle of a regular dodecagon is equal to 150°. This can be calculated by using the formula: 180n–360 n 180 n – 360 n, where n = the number of sides of the polygon. In a dodecagon, n = 12. Now substituting this value in the formula. 180(12)–360 12 = 150∘ 180 ( 12) – 360 12 = 150 ∘. The sum of the interior angles of a ...
