Linear pairs are angles that form a straight line, the angle measure of a straight line is 180 degrees, so … A linear pair forms a straight angle of 180 degrees, so you have two angles whose sum is given as 180, which means they are supplementary. What if intersecting lines are not supplementary, are they still linear pairs? Angles A and Z are supplementary because they add up to 180°. Linear pair or supplementary angles A pair of supplementary angles that form a straight line. Linear Pairs, Vertical Angles, and Supplementary Angles Definition: Two angles pBAD and pDAC are said to form a linear pair if and areAB JJJG AC JJJG opposite rays. 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.
