Issouf claims that the scale factor is 1/2. which statement about his claim is correct?

love history [14]

Answer:

The correct option is D.

Step-by-step explanation:

It is given that Issouf claims that the scale factor is 1/2.

From the given figure it is clear that

$CB'=C'B'=2$

$B'B=6$

$CB=CB'+B'B=2+4=6$

The scale factor of a figure is

$k=\frac{\text{Length of any side of image}}{\text{Length of corresponding side of preimage}}$

$k=\frac{C'B'}{CB}$

$k=\frac{2}{6}$

$k=\frac{1}{3}$

The scale factor is 1/3 because CB is actually 2 + 4 = 6.

Therefore the correct option is D.
