Representing Sets.
In Venn Diagrams.

A set can be represented diagrammatically using a circle or an ellipse.

The elements are written inside the circle / ellipse.

The name of the set is denoted by a capital letter written outside the circle, near to the circle.

Disjoint sets are represented by two separate circles.

Draw a Rectangle, that encloses the set.
