Chelating Ligands

The definition of a chelate as given in lecture is that it is a complex containing a ligand that forms a ring of atoms that includes the central metal atom. I don't understand how to apply this definition to the homework problems. If a ligand is polydentate, does that mean it is a chelating ligand? I don't know how to look at ligand/complex and determine if it is chelating...can someone explain?

I believe by polydenate it means the ligand can form three of more chelated rings

If a ligand is polydentate, then it is a chelating ligand. To determine if a ligand is polydentate, look at the number of electron pairs it can donate. If it is more than 1 electron pair, then it is polydentate
