Find the exterior angle
WebAnother way to calculate the exterior angle of a triangle is to subtract the angle of the vertex of interest from 180°. ... Using the law of sines makes it possible to find unknown angles and sides of a triangle given enough … 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.
