Triangle XYZ was dilated around the origin by a scale factor of 2/3 .
The original coordinates of XYZ are X (0, 3), Y (3, 6), and Z (-3, -9). What are the coordinates of the dilated image?
Quadrilateral S takes on a transformation that results in quadrilateral T, and the following are true.
* The corresponding angle measures of both quadrilaterals are congruent.
* The side lengths of quadrilateral T are twice as long as those of quadrilateral S.
Using the given information what transformation was done.
Rectangle FGHJ, shown below, is translated 6 units right and 1 unit up to produce rectangle F`G`H`J`.
Which statement about the side lengths of rectangle F`G`H`J` is true?
F`G` = 3, G`H` = 5
F`G` = 3, G`H` = 6
F`G` = 9, G`H` = 5
F`G` = 9, G`H` = 6
Mia enlarged a plan for an outdoor stage. The original plan is shown below.
She dilated the outdoor stage by a scale factor of four with the center of dilation at the origin. Which ordered pair will be the coordinates of one of the new vertices?
A dilation is which of the following:
Either an enlargment or a reduction
Neither an enlargement or a reduction
If the scale factor is less than one, the new figure will be
