What will be the order of increasing bond angle-Cl2O,ClO2,ClO2- ? Explain to me?

The increasing order of bond angle is as follows:
ClO2- < Cl2O < ClO2
Bond angles are as follows:
ClO2- : 110o
Cl2O: 110.88o
ClO2 : 117.40o
ClO2has 7+6+6+1=20 total valence electrons to distribute.
ClO2 has 7+6+6=19 total valence electrons to distribute.
Cl2O has oxygen at the center (with chlorine having its typical valency as a halogen), and has 7+7+6=20 total valence electrons to distribute.
