They need to be number C plus 3-2:7
Polygons are similar? Well there is no picture provided, so I have no idea what you're talking about. But I think you might be asking if in general all polygons are similar, and if that's the case, they are not. Similar means they are similar in at least one aspect, and all polygons are different from each other, only adding one line for each bigger polygon. So I don't know if this helped you, but I tried anyways.
This what it should look like. did you need the steps or no ?
A. Research
B. 50%
C. 15%
Hope this helps! Comment if you want a better explanation, have questions, or concerns! :)
