Answer:
The answer is A. P is a transversal line; 1 and 2 are corresponding angles
Step-by-step explanation:
The transversal is always gonna be the line that goes through the 2 parallel lines so that takes out C and D.
For angles 1 and 2 to be alt. int. angles, one angle would need to be on the other side of the transversal, which rules out B.
That leaves A, as P is the transversal of Q and R, and 1 and 2 are corresponding angles.
