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.
