Answer:
scale factor = 2
Step-by-step explanation:
given that Δ ABC and Δ DFE are similar , then the ratios of corresponding sides are in proportion.
The scale factor is the ratio of corresponding sides , image to original.
AC and DE are corresponding sides, then
scale factor = [tex]\frac{DE}{AC}[/tex] = [tex]\frac{6}{3}[/tex] = 2
