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 ... WebOctagon is an eight-sided two-dimensional geometrical figure. An octagon consists of 8 interior angles and 8 exterior angles. The sum of the interior angles of an octagon is 1080°, and the sum of its exterior angles is 360°. There are 20 diagonals in an octagon. Octagons are classified into various types based upon their sides and angles.
WebThe number of triangles is 1, 8, 35, 110, 287, 632, 1302, 2400, 4257, 6956 for polygons with 3 through 12 sides. Introduction.
