Describe the translation from shape
A to shape B.

First, let’s be entirely clear
about which shape is our object and which is our image. The translation takes us from shape
A to shape B. So, shape A is the object, and
shape B is the image. We can see that this movement then
will be to the left horizontally and up vertically. To work out the number of units A
has been translated by in each direction, we can pick a pair of corresponding
corners or vertices on the two shapes and then count the number of units moved.

Looking horizontally, because
remember we always describe the horizontal movement first, we can see that shape A
has been translated by seven units, and it’s to the left. The vertical movement is one unit,
and it is upwards. So, using words, we can describe
the translation from shape A to shape B as seven units left and one unit up. We could also pick another pair of
corresponding vertices on the two shapes to check our answer if we wish.
