100 points please help ! What is the name of the line of reflection for the pair of figures

Answer:
Hey!
I think the line must be LINE R
Step-by-step explanation:
As you can see it must be the Line of Reflection for both figures because it is EQUIDISTANT (equal distance from the 2 shapes). It runs PARALLEL in angle to the shapes too...
It can't be Line P because the line does not produce equal shapes on either side of it...
It can't be Line Q because it only provides the reflection result on one of the shapes, not BOTH...
So your answer is Line R
