Simmilarity and transformations
The smaller triangle is enlarged times two. AB and DE are similar but is enlarged times two. So when reading the figure u will read it ABC equal too DEF
Point ABC is transferred to the new cords which was just moved six unites to the right. So the figure is in another location
Similarity and Translation
If you put translation and dilation together and add a primage you will see how a figure is simmilar. And how it was able to turn.
