Translation­ when a figure is slid in any direction.

86

Translations can be close together...

or far apart.

They can slide diagonally from each other.

The figure changes in no other way.

Using the Dot boards to help you, drag the shape to a new location to create a Translation.

108

Rotation­ when a figure is turned or rotated around a single point.

119

Rotations always turn around a single point... and can 

rotate a little bit...

or a lot. They can even rotate around a point that does NOT touch the figure.

Using the Dot boards to help you, drag the shape and turn using the green handle to create a Rotation.

1311

Reflection­ when a figure is flipped over a line.

1412

Reflections can be close to or touch the line...

or they can be far from the line.

The line can be drawn in any direction...

or not drawn at all.

Now, use the graph paper to create a Translation, Rotation, and Reflection.  

You may choose the shape you use, but you must have one of each type of transformation labeled...also make sure your beginning shape is labeled.

Now, use the online pattern blocks to create a Translation, Rotation, and Reflection.
