The properties of adjacent angles given below help us identify them easily. POC = 90 If the sum of the measures is 90, then the given angles are complementary, if the sum of the measures is not 90, then the given angles are not complementary. So do 2 and 3 , 3 and 4 , and 1 and 4 . any two angles that add to be 180 degrees is complementary. It means that if two angles are supplementary, they do not necessarily form a linear pair of angles. In geometry, a linear pair of angles is a pair of adjacent angles formed when two lines intersect each other at a point. Hence, we can say that two right angles can form a linear pair. An angle is formed when two rays meet at a common endpoint and adjacent angles are those angles that are always placed next to each other. On subtracting the given angle from 180 we get the value of the other angle. Lie between the interior of the two lines. When two angles form a linear pair and the measurement of one angle is given then it is easy to find the value of the other angle using the linear pairs of angles property.
