Linear Pair Of Angles Two adjacent angles are said to form a linear pair of angles, if their non-common arms are two opposite rays.In the adjoining figure, ∠AOC and ∠BOC are two adjacent angles whose non-common arms OA and OB are two opposite rays, i.e., BOA is a line ∴ ∠AOC and ∠BOC form a linear pair of angles.Theorem 1: Prove that the sum of all the angles formed … [Read more...] about Linear Pair Of Angles
