Which statement is FALSE about reflections?

• Reflections create congruent images.

• In a reflection, the image is the same distance from the line of reflection as the pre-image.

• Reflections preserve orientation.

• Reflections preserve size.

Which statement is FALSE about dilations?

• Dilations preserve size.

• Dilations preserve shape.

• Dilations preserve orientation.

• Dilations can make smaller or larger images.
