1) Substitution from definition.
2) We use 
3) We are changing the order of 3 and 
.
4) We add 1 and 3 and we get 
5) Substitution from definition (but the other way than at the beginning).

Step-by-step explanation:
i created it that way so yall will take a longer time to answer
L and M are parallel, just like P and N because their angles with other segments are the same
