Answer 1

Note that after scaling, the triangle is still an equilateral triangle as before, and the only difference is that the side length is halved from 3.4 to 1.7 (3.4/2=1.7). Therefore, the scale factor is 1.7/3.4=0.5. A scale factor <1 means that the original shape is reduced (becomes smaller), so the scale factor is a reduction.

Answer 2

Answer:

The scale factor is $0.5$

Is a reduction

Step-by-step explanation:

we know that

The scale factor is the ratio of the corresponding side of resulting triangle by the corresponding side of the first triangle

Let

z-----> the scale factor

x------> the corresponding side of resulting triangle

y------> the corresponding side of the first triangle

so

$z=\frac{x}{y}$

In this problem we have

$x=1.7\ units$

$y=3.4\ units$

substitute

$z=\frac{1.7}{3.4}=0.5$

The scale factor is less than one

$0.5 < 1$

therefore

Is a reduction
