Explanation:

• Reflection: A transformation that maps a mirror image across a line.
• Preimage: The original image before a transformation.
• Image: The figure resulting from a transformation.
• Isometry: A transformation where the image and preimage are congruent.
• Prime Notation: Notation used to identify image points.
• Translation: A transformation that maps all points of a figure the same distance in the same direction.
• Rotation: A transformation where a geometric figure is turned about a fixed point.
• Line of Symmetry: A line that divides a figure into two pieces which are mirror images of each other.
• Composition: A combination of two or more transformations.
