Question

Which statement about the dilation of these triangles is true?

Answer 1

Given:

The figure of two triangles.

To find:

The scale factor.

Solution:

We know that,

$\text{Scale factor}=\dfrac{\text{Side of Image}}{\text{Corresponding side of original figure}}$

In the given figure,

$\text{Scale factor}=\dfrac{5(2)}{5}$

$\text{Scale factor}=2$

The scale factor is 2. Therefore, the correct option is B.
