ANSWER:
They are parallel lines since they share similar angles between 2 and 6
STEP-BY-STEP EXPLANATION:
Angles 4 and 6 are similar angles.
This is because 2 and 4 are similar and 4 and 6 are similar, therefore angles 6 and 2 are similar in the same way.
With this we can prove that m and n are parallel lines
