if two trees are identical

[Nwb4iNh0]

Why we pass two parameters/pointers in bool function when we want to create function to identify if two trees are identical ?
and when we call this function in main body we should call it with

bool areTreesIdentical (root1, root2)???

  bool areTreesIdentical(Node *a, Node *b)
