Hii I hope this helps! :)
Translation: It’s a transformation that moves every point in a figure the same distance in the same direction.
Rotation: It’s a a transformation that turns a figure about a fixed point.
Reflection: It’s a transformation that takes a shape/preimage and flips it across a line called the line of reflection to create a new shape/image.
I believe that the answer is 20. I am not entirely sure though.
R'S' is equal in length to RS.
length doesnt change, it was just rotated.
