Question

Choose a sequence of similarity transformations that maps ABC to DEF

Answer 1

A similarity transformation is one or more rigid transformations (reflection, rotation, translation) followed by a dilation.

When a figure is transformed by a similarity transformation, an image is created that is similar to the original figure

In this case, the sequence of transformation that maps ABC to DEF is as follow:

• Reflection across the x-axis

,

• A scale factor of 2

It is a reflection across the x-axis because the image is turned upside down and it is enlarged because:

$\frac{DE}{AC}=\frac{4}{2}=2$

Hence Option A is correct
