A translation moves a shape up, down or from side to side but it does not change its appearance in any other way.
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 of where x is the movement horizontally and y is the movement vertically. A positive value of x means a movement to the right and a negative value of x means a movement to the left. A positive value of y means a movement upwards and a negative value of y means a movement downwards.
