Answer:
It is reflection
Step-by-step explanation:
We know these three rules:
-a rotation followed by a rotation is a rotation
-a reflection followed by a reflection is also a rotation
-a rotation folowed by a reflection is a reflection
So we have: f3r3 is f (reflection)
f2 f is r (reflection)
r3 r is r
f2 r is f
r2 f is f
r1 f is f
So, r1r2f1r3f2f3r3 is reflection.
