Explanation: Supplementary angles are two angles whose same is 180o. Each pair form supplementary angles because their sum is 180^o. Report. A linear pair is a pair of adjacent angles formed when two lines intersect. If the sum of two angles are 180o then the angles are said to be supplementary angles,. 03/04/15. A linear pair (two angles that form a line) will always be supplementary. ∠1 and ∠3 are not vertical angles (they are a linear pair). Example: LINEAR PAIR Two angles that are adjacent and supplementary. The angles are. Often the two angles are adjacent, in which case they form a linear pair like this: Similar in concept are complementary angles, which add up to 90°.. A way to remember. So do ∠ 2 and ∠ 3, ∠ 3 and ∠ 4, and ∠ 1 and ∠ 4. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees. Hope you understand this.
