Answer:
Reflection; Translation; Dilation; Similar
Explanation:
Figure 1 is reflected because it is the same thing, just flipped, like a mirror.
Figure 2 is translated because it is the same exact shape, just moved
Figure 3 is dilated because it is the same thing, but shrunken down
Figure 1 is similar because it is not the same exact thing, but just a similar shape of it.
Hope this helps
