3
Orientation Definition: The orientation of a figure is the clockwise or counterclockwise labeling of the vertices. A A C C B B Clockwise Counterclockwise
4
Composition of Motion Definition: A Composition of Motion is a transformation in which a second transformation is performed on the image of a first transformation. Example: Translation by vector <5,-4> followed by reflection over x-axis Translation: (x, y) (x+5, y-4) Reflection over x-axis: (x, y) (x, -y) Putting them together: (x, y) (x+5, y-4) (x+5, -(y-4)) Written as one rule: (x, y) (x+5, -y+4)
5
Be Careful! While in some composition, the order won’t matter, in others, the order you perform the transformation DOES change the final result. Be sure to read each problem CAREFULLY!
6
Glide Reflection Definition: A Glide Reflection is the composition of a translation (glide) followed by a reflection in a line parallel to the translation vector.
