(iv) If angles forming a linear pair are equal, then each of these angles is of measure 90°. 14. Linear pair of angles are formed when two lines intersect each other at a single point. A linear pair is a pair of adjacent angles whose non-common sides are opposite rays. None of these. Since ∠2 and ∠4 are supplementary, then ∠2 + ∠4 = 180°. If two adjacent angles are complementary they form a right angle. So, we Lv 7. True only if the two angles are adjacent (i.e. Supplementary angles and linear pairs both add to 180°. (vii) If two lines are cut by a transversal, then each pair of corresponding angles are equal. 4. A linear pair is two angles that are adjacent and whose non-common sides form a straight line. But, all linear pairs are supplementary. If two adjacent angles are complementary they form a right angle. (iii) Angles forming a linear pair can both be acute angles. Not all supplementary angles form a linear pair. Two acute angles form a linear pair. if two angles are supplementary, then the sum of their measures is 180°. Thus, ∠1 + ∠2 amounts to 180o. 5.
