Question

What is the scale factor from ADEF to AABC? 10 6 20 12 А 7 14

Answer 1

Answer:

The scale factor is 1/2

Step-by-step explanation:

Given

$\triangle DE F$ and $\triangle ABC$

Required

The scale factor from $\triangle DE F$ to $\triangle ABC$

Take a corresponding side in both triangles.

We have:

$DE= 20$     $AB = 10$

The scale factor from $\triangle DE F$ to $\triangle ABC$ is:

$k =\frac{AB}{DE}$

$k =\frac{10}{20}$

$k =\frac{1}{2}$
