Question

A dilation maps DEF to D'E'F'. EF = 6 inches and E'F' = 3/5 inches. If DE = 8 inches, what is D'E’??

Answer 1

Answer:

  D'E' = 4/5

Step-by-step explanation:

Corresponding sides have the same scale factor (the dilation factor).

  D'E'/DE = E'F'/EF

  D'E' = (DE)(E'F'/EF) = 8((3/5)/6) . . . multiply by DE; substitute given values

  D'E' = 4/5
