Translations!

I really enjoyed doing this worksheet about translations.  I realize I'm a total math nerd, but I thought it was really interesting.  This is an example of the problems on the assignment. 






Having the graph paper made translations easy to understand, but it's pretty easy to do them without a graph.  If you are given the original coordinates of a shape, you can use the information given to find the new location of each coordinate.  I will use the information provided in the example above to explain.

Original coordinates:  H (4,3) W (4,0) and G (2,1)
Since the translation is along the line (x-2, y-3) you can perform each operation to the original coordinates to find the new coordinates.
H (4,3) and (x-2, y-3)
(4-2, 3-3)
H' (2,0)

Perform the operation for each coordinate provided to find the new coordinates of the translated figure.  New coordinates are labeled as prime and that's why there are apostrophes in all of them. 
H' (2,0) W' (2, -3) G' (0,-2)

The guy narrating the video looks like he'd be a cool person to hang out with.  Enjoy!
