Question

What is the scale factor from triangle ABC to triangle DEF A. 3 B.4 C.5 D6

Answer 1

Answer:

A

Step-by-step explanation:

The scale factor is measured as the ratio of corresponding sides between sides of ΔDEF and ΔABC, that is image to original, thus

$\frac{ED}{BA}$ = $\frac{6}{2}$ = 3

$\frac{DF}{AC}$ = $\frac{9}{3}$ = 3

$\frac{EF}{BC}$ = $\frac{10.83}{3.61}$ = 3

The scale factor of ΔABC → ΔDEF is 3
