WebFeb 3, 2016 · It can also be defined with some algebraic calculations based on the fact that a sum of all interior angles is (N −2) ⋅ 180o. Dividing the above by N we will obtain a value of an interior angle: (N − 2) ⋅ 180o N. Therefore, exterior angle of a regular polygon is 180o − (N − 2) ⋅ 180o N = 360o N Answer link WebNov 22, 2024 · If you want to calculate the regular polygon parameters directly from equations, all you need to know is the polygon shape and its side length: Area; area = n × a² × cot(π/n)/ 4 ; Where n- number of sides, a - side length.
