To make a translation you have to have a set of coordinate like (x+4,y+2) or (x-2,y+1) then you can find where the next shape of coordinates are.
If you have 2 shapes you have to find out which shape has the prime letter and which one is just the regular shape, after you find which shape is which you can just count where the regular letters are to the prime letters are and that is how you find the rule for the translation.
