You've probably seen supplementary angles ... as an example, two supplementary angles add up to 180 degrees to form a measure that splits the circle perfectly in half. Non-adjacent supplementary ...

Therefore, any adjacent angles contained within that 180 degree sweep will necessarily have to add up to 180. Complementary ... those three categories. These examples of adjacent angles will ...

complementary angles and vertical angles are all useful in studying geometry because they can be identified visually by the student or worker. However, there is no rule stating that adjacent angles ...
