There are two exterior angles at each vertex of the polygon, each determined by extending one of the two sides of the polygon that meet at the vertex; these two angles are vertical and hence are equal. We know that linear-pair-angles are supplementary. (Lesson 2.5) Examples of interior angles would be those labelled x and 60 º in the figure left. When two angles are supplementary, each angle is said to be the supplement of the other. If two parallel lines are cut by a transversal, each pair of corresponding angles are equal in measure.

Let x = measure of the smaller angle Then, 5x = measure of the larger angle So, x + 5x = 180 3. Two obtuse angles form a linear pair. Find the angle which is equal to its complement: 6. The supplement of an interior angle is called an exterior angle, that is, an interior angle and an exterior angle form a linear pair of angles. (i) Given, a∥ba∥b then ∠1 = ∠5 [Corresponding angles]. In the diagram below, ∠ABC and ∠DBE are supplementary since 30°+150°=180°, but they do not form a linear pair since they are not adjacent. They are supplementary because they always add to 180° and because they are adjacent, the two non-common legs form … When they say "linear" this means that the two angles form a straight line (or, 180 degrees). The measure of one angle is 51°more than 1\2 the measure of the other angle. (iii) Angles forming a linear pair can both be acute angles. 5 m ∠ 3 + m ∠ 4 = 180 ° Definition of supplementary angles.
