A translation moves a shape up, down or from side to side but it does not change its appearance in any other way.
Translation is an example of a transformation. A transformation is a way of changing the size or position of a shape.
Every point in the shape is translated the same distance in the same direction.
Column vectors are used to describe translations.
means translate the shape 4 squares to the right and 3 squares down.
means translate the shape 2 squares to the left and 1 square up.
Vectors are given in the form where is the movement horizontally and is the movement vertically. A positive value of means a movement to the right and a negative value of means a movement to the left. A positive value of means a movement upwards and a negative value of means a movement downwards.
Describe the transformation of the shape DEFG.
The shape has been translated by the vector . The shape has moved three units to the left and six units down.
