A pair of vertical angles can be complementary. These ARE Adjacent Angles. Vertical angles are also known as vertically opposite angles which means they share the same vertex and are formed when two lines cross. a straight angle contains 180 degress . Given:two angles are supplementary to each other. By definition, supplementary angles add up to 180° therefore they are linear pairs, if they are adjacent.
