Transformations: Review

Which is true about the transformation shown?

• The graph shows a translation, and the pre-image and the image are congruent.

• The graph shows a translation, and the pre-image and the image are similar (same shape, different size).

• The graph shows a reflection, and the pre-image and the image are similar (same shape, different size).
