Re: [Math4u] Please answer this question

No, it wouldn't, since in a Venn diagram, drawing circles on top of
each other means complete equality.
Before thinking about how to draw it, first think of how all the sets
of triangles are related to each other. For instance, if a particular
triangle is in set A:
- can it be in B also?
- or maybe it has to be in B as well?
After you have a clear idea about the relations between the different
sets, then you can start drawing the Venn diagram. If you don't know
what a Venn diagram looks like in the first place, just Google for a
couple of examples (select "Images" and use a search string such as
"venn diagram").
