Question

Quadrilateral H prime is the image of quadrilateral H after a sequence of transformations. If quadrilateral H prime is congruent to quadrilateral H, which transformations could have been used? a dilation by a scale factor of 2 followed by a reflection a rotation followed by a dilation by a scale factor of One-half a reflection, a translation of 1 unit left, and then a dilation by a scale factor of 3 a translation of 6 units down, a rotation, and then a reflection

Answer 1

9514 1404 393

Answer:

(d) a translation of 6 units down, a rotation, and then a reflection

Explanation:

Dilation by any scale factor other than 1 will prevent the original being congruent with its image. The only answer choice with no dilation is the one shown above.
