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.
