The parallelogram on the left was dilated by a scale factor of 2 about point P . It was then transformed in another way to produce the parallelogram on the right. Which identifies the transformation that occurred after the dilation?

a translation of 9 units to the right

a reflection across the x -axis

a reflection across the y -axis

Quadrilateral H ' is the image of quadrilateral H after a sequence of transformations. If quadrilateral H ' is congruent to quadrilateral H , which transformations could have been used?

a translation of 6 units down, a rotation, and then a reflection

a dilation by a scale factor of 2 followed by a reflection

a rotation followed by a dilation by a scale factor of 1/2

a reflection, a translation of 1 unit left, and then a dilation by a scale factor of 3

Triangle QNP was dilated by a scale factor of 1/3 about point P . It was then transformed in another way to produce triangle Q'N'P' Which identifies the transformation that occurred after the dilation?

a 180 degrees clockwise rotation about the origin

a reflection across the x -axis

a reflection across the y -axis

Which describes how triangle FGH could be transformed to triangle F'G'H' in two steps? Which identifies the transformation that occurred after the dilation?

a dilation by a scale factor of 4 and then a reflection across the x -axis

a dilation by a scale factor of 3 and then a reflection across the x -axis

a dilation by a scale factor of 3 and then a 180 degrees rotation about the origin

a dilation by a scale factor of 4 and then a 180 degrees rotation about the origin

A triangle is dilated by a scale factor of 1/5 and then rotated 90 degrees clockwise about the origin. Why is the image similar to the pre-image? Check all that apply.

The corresponding angles of the triangles are congruent.

The image is a reduction of the pre-image.

Neither the dilation nor the rotation change the shape of the triangle.

The corresponding sides of the triangles are congruent.

The corresponding sides of the image are 5 times as long as those of the pre-image.
