Answer:
B and F
Step-by-step explanation:
Angle 1 + Angle 2
Angle 3
Angle 4 + Angle 5 (choice F)
Angle 6 (choice B)
We eliminate choices (A), (D), and (E) as these would make p perpendicular to n rather than r. And we can eliminate choice (C) as Angles 3 and 6 are vertical angles, so they would have equal measure regardless of whether any of the lines were perpendicular. The correct answers are (B) and (F).
