Answer:
Step-by-step explanation:
There are lots of angles that you could use.
1 and 4
2 and 3
13 and 14
12 and 5
There are others.
5 and 6 will work. 5 is acute. 6 is obtuse. If r and s are meant to be parallel then those angles are the only ones that speak of r and s. The others will make p and q parallel.
