Question

question 9 of 10
what is the scale factor from \\( \triangle a b c \\) to \\( \triangle d e f \\)?

a. 5
b. 10
c. 0
d. 1

Explanation:

Step1: Recall the formula for scale factor

The scale factor from $\triangle ABC$ to $\triangle DEF$ is given by $\frac{\text{side length of }\triangle DEF}{\text{side length of }\triangle ABC}$.

Step2: Substitute the side lengths

Here, side length of $\triangle ABC = 5$ and side length of $\triangle DEF=5$. So, scale factor $=\frac{5}{5}$.

Step3: Simplify the fraction

$\frac{5}{5}=1$.

Answer:

D. 1
