Each figure is an isometry image of the figure below. Are the orientations of the preimage and image the same or opposite? What type of isometry maps the preimage to the image?
The orientations are opposite. The image is not a simple reflection of the preimage. The isometry that leads to opposite orientation but is not a reflection is a glide reflection.
How do the arrows in the preimage and image help you?
Compare the directions of the arrows (counterclockwise or clockwise) to determine if the orientations of the figures are the same or different.
The orientations are the same. The image is not a translation of the preimage. The isometry that leads to the same orientation but is not a translation is a rotation.
Each figure is an isometry image of the figure below. Are the orientations of the preimage and image the same or opposite? What type of isometry maps the preimage to the image?
Describe the image of Z reflected first across line a and then across line b.
