Did You Know?

You can describe a motion used to move a plane figure as a translation (slide), reflection (flip) or rotation (turn).  The motion
does not change the size or shape of the figure.  It only results in a change of location.


Check What You Know First

Look at the figures below and write the following answers:  translation, reflection or rotation.  Remember a translation
is a slide, a reflection is a flip and a rotation is a turn.

Key Vocabulary

Transformation  - The movement of a figure by a translation (slide), reflection (flip) or rotation (turn).

Translation (Slide) -   A movement of a figure to a new position without turning or flipping it.

Reflection (Flip) -   A movement of a figure to a new position by flipping the figure over a line.

Rotation (Turn) -   A movement of a figure to a new position by rotating the figure around a point.

 

Learn About It Now

 A transformation is the movement of a figure by a translation (slide), reflection (flip) or rotation (turn).

Let’s look at the figures below to see what that means.

 

A translation (slide) is a movement of a figure to a new position without turning or flipping it.   The following figures are
examples of translations (slides), which were numbers 3 and 5 in the problems you did.

 

A reflection (flip) is a movement of a figure to a new position by flipping the figure over a line.  The following figures are examples
of reflections (flips), which were numbers 1 and 6 in the problems you did.

 

A rotation (turn) is a movement of a figure to a new position by rotating the figure around a point. The following figures are
examples of rotations (turns), which were numbers 2 and 4 in the problems you did.

 

 

Activity to Practice Making a Translation (Slide), Reflection (Flip) or Rotation (Turn)

Use pattern blocks to do this activity.  Choose a pattern block to show different ways to move the block. 
Then select a different pattern block and repeat the steps.

 

More Practice With Translations (Slides), Reflections (Flips) or Rotations (Turns)

Look at the figures below and write the following answers:  translation, reflection or rotation.  Remember
a translation is a slide, a reflection is a flip and a rotation is a turn.  There are two questions that can have two answers. 
See if you can figure out which ones.
