can you please help

==================================================
Explanation:
We have four lines that form 4 intersection points. Let's label these points A,B,C, and D. Check out the diagram below.
We can say that angle 1 is a corresponding angle to angle 9 because
Similarly, angles 4 and 12 are corresponding as well. They are both in the east quadrant and point A is adjacent to point B. A similar thing happens with angles 5 and 7.
In contrast, angles 6 and 16 are not corresponding angles. Yes they are both in the south quadrants of their four corner configuration, but point A is not adjacent to point C. Angle 6 corresponds to only angle 14 and angle 8, but not angle 16.
