Parallelogram DEFG is transformed to parallelogram VSTU.

Parallelogram D E F G is reflected diagonally to form parallelogram V S T U.

Which statement about the transformation is true?
Parallelogram DEFG is the pre-image because it is not the result of the transformation.
Parallelogram DEFG is the image because it is the result of the transformation.
Parallelogram VSTU is the pre-image because it is the result of the transformation.
Parallelogram VSTU is the image because it is not the result of the transformation.

1 answer

In the context of transformations, the term "pre-image" refers to the original shape before a transformation has been applied, while the term "image" refers to the shape after the transformation.

Since parallelogram DEFG has been transformed to parallelogram VSTU through reflection, the following is true:

  • Parallelogram DEFG is the pre-image because it is the original shape before the transformation.
  • Parallelogram VSTU is the image because it is the result of the transformation.

Therefore, the correct statement from your list is:

Parallelogram DEFG is the pre-image because it is not the result of the transformation.
