However, if such segments are drawn in a concave polygon, some part of it might lie on the exterior. Answer and Explanation:1 The interior angles of ann−sided convex polygon add up to(n−2)180∘. There arenexterior and interior ang...
As there are twelve identical interior angles, the sum of all the interior angles of a dodecagon equals 1800°. We can also easily deduce that the exterior angle, β, has 30°, because it satisfies α + β = 180°. Note that these angles remain the same no matter the side length of...
