WebExterior angle = Sum of Interior opposite angles. In this case, the exterior angle, ∠VUX = ∠UTV + ∠UVT. ∠VUX = 53 ∘ + 103 ∘ [Substituting the value of interior angles] ∠VUX = … WebExterior Angle Theorem Examples. Example 1: Find the values of x and y by using the exterior angle theorem of a triangle. Solution: ∠x is the exterior angle. ∠x + 92 = 180º (linear pair of angles) ∠x = 180 - 92 = 88º. Applying the exterior angle theorem, we get, ∠y + 41 = 88. ∠y = 88 - 41 = 47º. Therefore, the values of x and y are ...
WebTherefore, exterior angles are formed outside a triangle between one side of a triangle and the extended side. Each exterior angle is adjacent to an interior angle. Adjacent angles are angles with a common vertex and side. The figure below shows the angle of a triangle. The interior angles are a, b and c, while exterior angles are d, e, and f.
WebThe sum of angles in a triangle are 180, and if you have an iscoseles triangle, the angles opposite the congruent sides are congruent also. So if you have x as one of the angles opposite and a vertex angle of x + 30, the other opposite angle is also x, so x + x + x+ 30 = 180 which you can solve. ... That's why he makes these videos.
