Answer
N=N=N bond angles in Hydrogen azide: $120^{\circ}$ and $180^{\circ}$
N to N to N bond angles in cyclotriazene: $60^{\circ}, 60^{\circ}$ and $109.5^{\circ}$
Work Step by Step
The distortion in the N=N bond angle in hydrogen azide is due to the lone pair of electrons. Bond angles of N to N to N bonds in cyclotriazene are due to the cyclic shape.
