**Go through this page to learn more about transformation. It is all around you. Did you are doing transformations everyday without realizing you are doing it? That's correct!**

**Types of Transformations**

**Activity**

Make interactive papers to go inside your interactive notebook as you learn about transformations.

Make a 4 flap interactive foldable. You can make an extra section on the top or on the side for the title,

*TRANSFORMATIONS*. On the front of each flap, write:

*Translation*,

*Rotation*,

*Reflection*, and

*Dilation*. In the inside of the interactive, define the types of transformation and give examples of each. You will find these definitions on this page or the links listed on this page.

Use lots of color. Write anything found on this page or on the web in your interactive notebook that relates the transformations. If you prefer, you can just write these terms and definitions using lots of color instead making an interactive.

Note: The default setting is too slowly. I find it easier to watch at the speed of 1.25. To do this, go to "Settings" (it is next to "CC"). Select "1.25" under "Speed". This should be a better setting.

**Translation**

__Translation:__A translation slides or moves an object along a straight line.

Translate = Slide or Move

Slide Slide Slide

Move

Translations, An interactive activity: Mathwarehouse

**Activity**

Place a book on a table, desk, or floor.

Move the book in a straight line to another location without picking the book up.

Repeat this process several times or until you understand this type of transformation.

Translations and Rotations: Geogebra

**Activity**

Grab some graph paper. Make your own shapes. You can use the instructions at: Transformation Geometry (Translations, Rotations, Reflections): YouTube or quietube: Transformation Geometry (Translations, Rotations, Reflections) to complete your own translation transformation.

**Rotation**

__Rotation:__A rotation turns a shape by turning it around a fixed point.

Rotate = Turn

Turn, Turn, Turn

**Activity**

Grab some graph paper. Make your own shapes. You can use the instructions at: Transformation Geometry (Translations, Rotations, Reflections): YouTube to complete your own translation transformation.

**Reflection**

__Reflection:__A reflection flips a shape over a line.

Reflect = Flip

This is like reflecting in a mirror. You flip the image. If you have a number 7 on your shirt, it will flip.

Flip, Flip, Flip

When you translate, rotate, or reflect an object, they are all

**CONGRUENT**.

**Congruent**

__Congruent:__Congruent is when a shape has the same size and shape.

Same size, same shape

Same size, same shape

Same size, same shape

**Activity:**Cut out a small piece of paper and fold it in half. On the front write

*Congruent*. Inside behind the title, define what it is, and on the next part, give examples.

After you do these three types of transformations, the shape is still the same shape and size.

Now, you can perform the next type of transformation which is called dilation.

**Dilation**

__Dilation:__A dilation is to make something larger or smaller.

Larger or smaller

Larger or smaller

Larger or smaller

A dilation is a similarity transformation (or a similarity).

You use dilation to show that objects are

**SIMILAR**even though they are different sizes.

__Steps to Dilation__:1. Multiply both coordinates by scale factor

2. Simplify

3. Graph (if required)

**Activity**

To understand dilation, grab some graph paper.

Draw a shape. It can be a triangle, square, rectangle, etc.

Follow the above steps, "Steps to Dilation", to make an object larger.

Repeat with different shapes.

Let's review some terms and definitions about transformation.

__Translation:__A translation moves or slides an object along a straight line.

__Rotation:__A rotation turns a shape.

__Reflection:__A reflection flips a shape over a line.

__Congruent:__Congruent is when a shape has the same size and shape.

__Dilation:__A dilation is to make something larger or smaller.

Now you know more about transformations. Enjoy transformations in your daily life. :0)
