# Intersection of Sets

**Example :** 1, 3, 5, 7 and 9 are distinct objects when they are considered separately and collectively they form a single set of size five. Written as {1, 3, 5, 7, 9}. Intersection of sets is the set of elements which are common in all the sets. The symbol used to denote intersection is $\cap$. In this page we will learn intersection of two sets, intersection of three sets, intersection of open sets, intersection of convex sets and few examples on intersection of sets.
