Measure of each exterior angle of a triangle

WebApr 10, 2024 · The exterior angle theorem for triangles states that the sum of “The measure of an exterior angle of a triangle is equal to the sum of the measures of the two interior angles that are not adjacent to it; this is the exterior angle theorem. The sum of the measures of the three exterior angles (one for each vertex) of any triangle is $360$ … 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.
