Exploring Reflections in Rigid Motions

What is a reflection in the context of geometric transformations?

• A process to translate figures from one location to another

• A technique for scaling figures larger or smaller

• A type of transformation that mirrors a figure across a line

• A method to rotate figures around a point

What is the role of the line of reflection in the geometry of reflections?
