A translation is a type of rigid transformation, which means it changes the position or orientation of an image without changing its size or shape.

Just like how we have up/down and left/right buttons to control the movement of a video game character, we can use translations to control the movement of an image:

Translation:

$($

$0$

$,$$0$

$)$A translation is a set of directions in the form of a point

$($$xchange$$,$$ychange$$)$

or a description ($x$ units right/left and $y$ units up/down) that tells us how to move an image or shape.Adding the translation to each original point of the image gives us the new points of the image.

$original points+translation=new points$

## How to Do Translations

### Step 1. Identify the translation.

How is the translation described?

### Step 2. Identify the original points.

$original points=(x_{1},y_{1}),(x_{2},y_{2}),...,(x_{n},y_{n})$

### Step 3. Add the translation to the original points to get the new points.

Original Point | $+$ | Translation | $=$ | New Point |

$(x_{1},y_{1})$ | $+$ | $(x,y)$ | $=$ | $(x_{1}+x,y_{1}+y)$ |

$(x_{2},y_{2})$ | $+$ | $(x,y)$ | $=$ | $(x_{2}+x,y_{2}+y)$ |

... | ... | ... | ... | ... |

$(x_{n},y_{n})$ | $+$ | $(x,y)$ | $=$ | $(x_{n}+x,y_{n}+y)$ |

### Step 4. Plot the new points and connect the dots.
