In geometry, what does translation mean?

Hi,  It means to move from one place to another.  For example, you 
could move the circle of radius 3 centered at the origin point (0,0) 
to another location, like with center at (-7,11). Then its equation 
would change to (X+7)^2 + (Y-11)^2 = 9 from the X^2 + Y^2 = 9 
original.  

Of course there are other uses of the word. Translation from English 
to Japanese, for example. Also, if a lawyer starts talking about "the 
party of the first part ...etc." you might ask for that to be 
translated (from legal English) into English.
  
The common thread here is that all uses of "translation" involve a 
change from one place or state or form to another.  
  
I hope this helps.  If you need more info on translations or 
other kinds of geometric transformations, just write back.
