Question

Study the two equilateral triangles shown.By what factor is Triangle 1 reduced to form Triangle 2?

Answer 1

0.75

Step-by-step explanation

We have that the two triangles are equilateral, which implies they are similar.

To find the scale factor by which Triangle 1 was reduced to form Triangle 2, we have to divide the given length of Triangle 2 by that of Triangle 1.

That is:

`\begin{gathered} \text{Scale Factor = }(7.5)/(10) \\ \text{Scale Factor = 0.75} \end{gathered}`

That is the factor.
