WebThe size of each interior angle of a polygon is given by; Measure of each interior angle = 180° * (n – 2)/n where n = number of sides. Examples Size of the interior angle of a decagon. A decagon is a 10 -sided polygon. n = 10 Measure of each interior angle = 180° * (n – 2)/n Substitution. = 180° * (10 – 2)/10 = 180° * 8/10 = 18° * 8 = 144° WebJan 28, 2016 · Now we can calculate the measure of each interior angle, it is 1 N -th of the above value, that is N − 2 N ⋅ 180o. Knowing interior angle we can find exterior by subtracting interior angle from 180o . So, exterior angle is. 180o − N − 2 N ⋅ 180o = 180o ⋅ (1 − N −2 N) = 360o N. This result could've been obtained more ...
