Missouri department of revenue | Jun 10, 2021 ... An exterior angle of a triangle is equal to the sum of its two opposite non-adjacent interior angles. The exterior angle theorem states that the ...Example: Find the value of x in the triangle shown below. 106 ∘ x ∘ 42 ∘. We can use the following equation to represent the triangle: x ∘ + 42 ∘ + 106 ∘ = 180 ∘. The missing angle is 180 ∘ minus the measures of the other two angles: x ∘ = 180 ∘ − 106 ∘ − 42 ∘. x = 32. The missing angle is 32 ∘ .An exterior angle of a triangle is an angle formed by one side of the triangle and the extension of an adjacent side of the triangle. • Every triangle has 6 exterior angles, two at each vertex. • Angles 1 through 6 are exterior angles. • Notice that the "outside" angles that are "vertical" to the angles inside the triangle are NOT called ... ...
