Statement
Justification
angle 2 = angle 6
Corresponding angles of parallel lines are congruent.
angle 2 = angle 4
?
angle 4 = angle 6
transitive property of equality, 
angle 2  = angle 6, 
angle 2 = angle 4, 
therefore angle 4 = angle 6
  
Which is the missing justification?

 Angles 1 and 3 are supplementary; therefore, angle 2 is equal to angle 4.

 Angles 1 and 3 are congruent; therefore, angle 2 is equal to angle 4.

 Angles 1 and 4 and angles 1 and 2 are supplementary; therefore, angle 2 is equal to angle 4.

 Angles 1 and 4 and angles 1 and 2 are congruent; therefore, angle 2 is equal to angle 4.
