# two angles that are supplementary are always linear pairs

Linear pairs are adjacent and supplementary. What is the difference between complementary and supplementary angles? Two adjacent angles are said to form a linear pair angles, if their non-common arms are two opposite rays. And two intersection lines always create four linear pairs of angles (draw a picture). Supplementary Angles are two angles the sum of whose measures is 180º. Linear Pair of Angles. Linear pairsget their name because the sides not common to the two angles form a straight line. Linear pairs are angles that form a straight line, the angle measure of a straight line is 180 degrees, so linear pairs must be supplementary.
