Go through this page to learn more about transformation. It is all around you. Did you know you are doing transformations everyday of your life without realizing 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.
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.
What type of transformation is this?
Double click on the below rectangle to reveal the answer. TRANSLATION Play this Interactive Game Translations and Rotations: Geogebra
Activity
Place a book on a table, desk, or floor.
Move the book to the left or right.
Repeat this process several times or until you understand this type of transformation.
What type of transformation is this?
Double click on the below rectangle to reveal the answer. ROTATION Play these Interactive Games Translations and Rotations: Geogebra Rotation about a point ON the triangle Geogebra
Activity
Place a book on a table, desk, or floor.
Flip the book to direct opposite side of where it was originally.
Repeat this process several times or until you understand this type of transformation.
Double click on the below rectangle to reveal the answer. REFLECTION Play these Interactive Games Reflections: Geogebra Reflection of the plane about a line
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 an object along a straight line. Rotation: A rotation moves a shape by turning it around a fixed point. 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. Have fun doing transformations!!!
