\mathbb{ELLO \ THERE!}

--------

WAYS to CHECK If l║m

If CORRESPONDING angles are equal, l║m.

If co-interior angles are equal, l║m.

If alternate interior angles are equal, l║m.

If any ONE condition is OBEYED, we can tell the lines are parallel.

---------

First lets find angles that are able to be found.

∠PQS + 60° = 180° (Linear pair)

∠PQS = 180° - 60°

∠PQS = 120°

Now, we can see that corresponding angles PQS and PQM are equal,

Since corresponding angles are equal the lines are parallel!
