Each triangle in the diagram is a reflection of another triangle across one of the given lines. How can you describe Triangle 2 by using a reflection rule?

I. Rl (Triangle 3)
II. Rm(Triangle 2)
III. Rm (Triangle 1)

A. I only
B. I and III only
C. II and III only
D. I, II, and III
(I put C. but it was wrong, now i'm thinking A.?)
