From the question, we are asked to find the images that are similar to polygon 1.
So, we have given that polygon 1 is from similarity transformations.
First let's note that polygons are similar if they are are exactly the same shape but can be different sizes.
We can see from the given polygon 1 is similar to polygon 1 is similar to polygon 3 and polygon 4, because these have same shape but different size.
Polygon 3 is orientation of polygon 1
Therefore, Polygon 3 and Polygon 4 are similar to
