What do you notice about the changes in the value in the coordinates after the translation? Can you use
addition and subtraction to work out the coordinates of the Image from the original coordinates?

O Translate triangle XY2 8 units to the left and
2 units down. Draw the image of the triangle
after translation and label its vertices as X', Y'
and Z' on the coordinate grid. Then write the
coordinates of X', Y' and Z'. Use a piece of
graph paper to help you.

Translate polygon WXYZ 7 units down and
4 units to the right. Draw the image of
the polygon after translation and label its V/
vertices as W', X', Y' and Z' on the coordinate
grid. Then write the coordinates of W', X', Y'
and Z'.
