PRIMAVERA - How to add predecessors and successors in p-6?

In Primavera 6, there are two types of activities based on relationships i.e Predecessors and Successors. 

Predecessor and successor 

A relationship defines how one activity relates to the start or finish of another activity or assignment.

These relationships, which form the logic of the project network, are used along with the activity duration to determine schedule dates.
