What is a reflection in geometry?

Back

A reflection is a transformation that flips a shape over a line, creating a mirror image.

How can you identify a translation on a graph?

Back

A translation can be identified by the parallel movement of a shape without changing its size or orientation.

What is the difference between a translation and a reflection?

Back

A translation moves a shape without changing its orientation, while a reflection flips it over a line.
