Answer:

Given, OA, OB, OC and OD are rays in the anticlockwise direction.

∠ AOB = ∠COD = 100°

∠BOC = 82°

∠AOD = 78°

We have to determine if AOC and BOD are lines or not.

If AOC is a line the linear pair of angles must be equal to 180°

So, ∠AOB + ∠COB = ∠AOC

∠AOC = 110° + 82°

∠AOC = 192°

∠AOC is not equal to 180°

Therefore, AOC is not a line.

Similarly, ∠BOC + ∠COD = ∠BOD

∠BOD = 82° + 100°

∠BOD = 182°

∠BOD is not equal to 180°

Therefore, BOD is not a line.

Thank uhhh :)
