A Venn diagram is diagram that shows possible logical relations between finite collection of different sets. The most common Venn diagram contains 2 sets or 3 sets.

Let’s see how can we use Venn diagram to find the relation of sets.

For example, Suppose we have 2 sets A and B, With Venn diagram we can find:

- Whether the A is equal to B
- Whether the A is superset of B
- Whether the A is subset of B
- None of the above

Let’s see some examples:
