Question

D’ E’ F’ G’ is a dilation image of DEFG. Which is the correct description of the dilation?A) canter F and scale factor 3B) center D and scale factor 2C) center D and scale factor 1/2D) center F and scale factor 1/3

Answer 1

For this case we have a polygon D’ E’ F’ G’ and a dilation DEFG so then the best description:

D) center F and scale factor 1/3

Since the total lenght of the base is 14+7=21

And the area covered by the blue polygon is 1/3 of the red one
