Aim:How do we use other definitions transformations?


Glide Reflection: The combination of a reflection in a line and a translation along that line.




Orientation: Refers to the arrangements of the points, relative to one another , after a transformation has occured.


Invariant: A figure or property that remains unchanged under a transformation of the plane is referred to as invariant. (something that stays the same and doesn't change)


An opposite isometry changes the order.




A direct isometry preserves orientation the letters go in the same clockwise and counterclockwise direction on the firgure and its image.
