Question

(3) Sum of two adjacent angles are said to form___________
if their non-common arms are two opposite rays​

Answer 1

Answer:

Linear pairs of angles

Answer 2

Answer:

Linear Pair Angles : Two adjacent angles are said to form a linear pair of angles, if their non-common arms are two opposite rays. Here, OA and OB are two opposite rays and ∠AOC and ∠BOC are the adjacent angles. Therefore, ∠AOC and ∠BOC form a linear pair. The sum of the angles in a linear pair is 180 0.
