Translational Symmetry

Look at the picture of the letter W below.
          W
Notice that it looks like two letter V's next to each other. If we took a scissors and cut the W right down the middle, we would have two identical pieces:
                    

Now look at the picture of the totem pole.

          
Notice that it has a repeated pattern, too. The same picture of a head is repeated four times. If we cut this picture between the heads, we would end up with four identical pictures of a head:
                    
If we can cut a picture into a straight line sequence of identical pieces, we say that the picture has translational symmetry. The line that marks where we cut the picture is called the line of translation. Draw one or more lines of translation for each these pictures:
