Question

What is the scale factor of triangle ABC to triangle DEF

Answer 1

$\bf side:side\qquad \cfrac{side}{side}\implies \cfrac{5}{5}\implies \cfrac{1}{1}\implies 1:1\impliedby \textit{scale factor}$

Answer 2

Answer:

The correct option is:  1

Step-by-step explanation:

Scale factor is the ratio of corresponding side lengths of two triangles.

Here....

$\frac{DE}{AB}=\frac{5}{5}=1\\ \\ \frac{DF}{AC}=\frac{5}{5}=1\\ \\ \frac{EF}{BC}=\frac{5}{5}=1$

So, the scale factor of $\triangle ABC$ to $\triangle DEF$ is 1.
