Answer:
<h2>∠2 ≅ ∠6</h2>
Step-by-step explanation:
To determine the parallelism between to lines, we have to demonstrate that their angle of direction are congruent. So, according to that, there are only two possible choices, the congruence ones, but only the first one ∠2 ≅ ∠6 make sense, because ∠2 is the direction of line q, and ∠6 represents the direction of line p.
Therefore, the correct answer is the first one, because demonstrate the congruence between both direction angles.
