Question

I really need help with this calculate the scale factor of DEF to ABC.

Answer 1

Given

To find the scale factor of triangle DEF to triangle ABC.

Step-by-step explanation:

It is known that,

When two triangles are similar the reduced ratio of any two corresponding sides is called the scale factor of the similar triangles.

From, the figure

That implies,

`\begin{gathered} Scale\text{ }factor=(75)/(15) \\ =(5)/(1) \\ =5:1 \end{gathered}`

Hence, the scale factor of triangle DEF to triangle ABC is 5:1.
