Transformations 

Ten transformation rule review QUIZLET 

Rigid Motions in a plane

Translations 

Reflections

Horizontal Translation

Vertical Translation

Diagonal Translation

Horizontal reflection

Vertical reflection

Reflect over y = x

​Reflect over y = -x

Reflect over x = n 
This is a HORIZONTAL reflection over a vertical line

Reflect over y = m 
This is a VERTICAL reflection over a horizontal line

Reflect over x = n AND y = m 

Reflect over ANY line

Two Reflections Make a Rotation

Rotations ABOUT ORIGIN

90 degree counterclockwise rotation 

180 degree counterclockwise rotation 

270 degree counterclockwise rotation


​Rotating by 90 degree CCW increments

Rotating CCW by ANY degree

Rotations NOT about ORIGIN

Rotational Symmetry 

Multiple Transformations 

Mona Lisa Transformations 

Two Rotations 

Reflect and Rotate 

Two Reflections and ONE rotation

Translation and a Rotation

Glide Reflections with CATS

Glide Reflections WALK on the beach

Glide Reflection is NOT a rotation


​Glide Reflections WOW

Glide Reflections TWO Triangles

Glide Reflections Does order matter?
