The exterior angle theorem is Proposition 1.16 in Euclid's Elements, which states that the measure of an exterior angle of a triangle is greater than either of the measures of the remote interior angles. This is a fundamental result in absolute geometry because its proof does not depend upon the parallel postulate. In several high school treatments of geometry, the term "exterior angle theorem" has been appli… WebWe can use the following equation to represent the triangle: x^\circ + 42^\circ + 106^\circ = 180^\circ x∘ + 42∘ + 106∘ = 180∘ The missing angle is 180^\circ 180∘ minus the measures of the other two angles: x^\circ = …
WebAn exterior angle must form a linear pair with an interior angle. This means that the exterior angle must be adjacent to an interior angle (right next to it - they must share a side) and the interior and exterior angles form a straight line (180 degrees). If you extend one of the sides of the triangle, it will form an exterior angle.
