As the s-character of hybrid orbital increases, the bond angle

As the s-character in hybrid orbital $\uparrow$, the bond angle rises $\uparrow$

 S-character is $50\%,\mathrm{p}$-character is $50\%$ and bond angle is $180°$.

S-character is 33.3 % ,P -character is 66.7% and bond angle is  120⁰

S-character is 25%,P -character is 75% and bond angle is 109⁰.28
