Question

Which of the following transformations will produce similar figures? Select all that apply.

Answer 1

The figures will be similar (and also congruent) for the transformations ...
  (-x, y)
  (x+2, y-5)
  (x, y)


_____
The transformation (2x, 4y) expands the figure twice as much in the vertical direction as in the horizontal direction. The result will not be similar to the original.
