Question

DEF is a dilation image of ABC. What is the scale factor?

a.) 1/2

b.) 2

c.) 1/4

d.) 2/3

Answer 1

I believe its A . 1/2

Answer 2

The scale factor is
`(1)/(2)`

Explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal and is called the scale factor

Let

z------> the scale factor

so

`z=(DE)/(AB)`

we have

observing the graph

`DE=4\ units`

`AB=8\ units`

substitute

`z=(4)/(8)=(1)/(2)`

The scale factor is less than one

therefore

Is a reduction
