Question

Trapezoid W'X'Y'Z' is the image of trapezoid WXYZ

under a dilation through point C.

What scale factor was used in the dilation?

1.) -6/5
2.) -5/6
3.) 5/6
4.) 6/5

Answer 1

W'X' is the dilated image, which is smaller than the original, so the scale factor would be less than 1.

Set up a ratio of the dilated figure to the original:

15/18 divide this by 3 to get 5/6

The answer is 3) 5/6
