Next, we'll use a two-column proof to prove another theorem: Congruent Supplements Theorem—If two angles are supplementary to the same angle, then the two angles are congruent. A linear pair is two angles that are adjacent and whose non-common sides form a straight line. A linear pair forms a straight angle which contains 180º, so you have 2 angles whose measures add to 180, which means they are supplementary. Example 2: the angles form a line (linear pair) therefore they are supplementary Example 3: the angles can be non-adjacent as long as their sum is 180° 110°+ 70° = 180° The sum is 180° therefore they are supplementary. soon. Since ∠2 and ∠4 are supplementary, then ∠2 + ∠4 = 180°. 2 ; 180-1 ; Are 180 and are supplementary angle also. Let one of the angle forming a linear-pair be 'x' and other be y. Hence ()x+47c and ()y+43c form a supplementary pair. Find the angles?
