Welcome to the forum.
A picture speaks a thousand words. See below (click to make bigger).
The blue region is A intersect B.
The union is all in both circles.
Now what happens if you slide one circle so it coincides with the other?

]]>If the two sets are equal then the union of them is the set itself and the intersection of them is the set itself so the answer is yes.
]]>IF A=B then is A union B = A intersection B ??
I would love to know your logic behind the same.
Note : A and B can be any two types of sets.
