Answer: 6) Vertical angles
7) Linear pair
8) Linear pair
Step-by-step explanation:
Since we have given that
6) ∠LSM and ∠OSN
The type of angle pair would vertically opposite angles.
As only one vertex is common So, it would be vertically opposites angles.
Hence, Option '4' is correct.
7) ∠LMS and ∠SMN are linear pair as it has two vertex in common.
Hence, Option '2' is correct.
8) ∠NSM and ∠MSL are linear pair as it has again two vertex in common.
Hence, Option '2' is correct.
