Teacher Notes    
 

CONCEPT 1 - Given a geometric figure and a rotation, reflection, or translation, draw the transformed figure using, e.g., graph paper, tracing paper, or geometry software.

 

We learn a lot about transformations when we analyze their motions in the coordinate plane.  Patterns reveal shortcuts/rules that allow us to quickly determine the coordinates of an image.

 

REFLECTION ON THE COORDINATE GRID

 

TEACHER NOTE -- These are great relationships to determine using patty paper and a few examples.

 

 

 

 

ROTATION ON THE COORDINATE GRID

 

TEACHER NOTE -- Rotations are much harder for students to see and determine the relationships. Patty paper makes it much easier for students.
