Decagon one exterior angle
WebOne interior angle in a regular triacontagon is 168 degrees, meaning that one exterior angle would be 12°. The triacontagon is the largest regular polygon whose interior angle is the sum of the interior angles of smaller polygons : 168° is the sum of the interior angles of the equilateral triangle (60°) and the regular pentagon (108°). WebSince each exterior angle and interior angle form a linear pair, one exterior angle of a decagon = 180 - 144 = 36°. We know that a decagon had 10 exterior angles, so, 10 × 36 = 360°. Hence, it is seen that the sum of the exterior angles of a decagon is 360°. Therefore, the sum of the exterior angles of a decagon is 360°.
