In the trigger, before executing your code keep a check that the variable is true or not.
We shoud avoid the recursive trigger.
Not aware if there is something like Circular Trigger but it can be as if we fire a trigger on Account insertion and a contact is created.Another trigger on contact object, when we insert contact record then account also inserted.
If a trigger is called again and again than it is called a recursive trigger.
For Eg:
trigger on Contact (before update){
update anyContactList;
}
In the above example, we are updating contact list in before update trigger so it will again call the trigger and our trigger will be called recursively till we stop or block it with the help of a static variable. Circular and recursive triggers are basically the same.
1. Many Developers face recursive trigger or recursive update trigger. For example in ‘after update’ trigger, Developer is performing update operation and this lead to the recursive call.
2. You want to write a trigger that creates a new record; however, that record may then cause another trigger to fire, which in turn causes another to fire, and so on.
Hope this helps

If the problem is caused by the same trigger, then we call that as a recursive trigger, On the other hand, if the problem is caused by other trigger and make infinite loops, then we call this as Circular trigger.
We can handle both, by creating a class with a boolean flag.
