From figure

\mathrm{\begin{aligned} & \angle \mathrm{AC}_1 \mathrm{~B}=\angle \mathrm{AC}_2 \mathrm{~B}=\angle \mathrm{AC}_3 \mathrm{~B}= \\ & \Rightarrow \angle \mathrm{PC}_1 \mathrm{~B}=\angle \mathrm{PC}_2 \mathrm{~B}=\angle \mathrm{PC}_3 \mathrm{~B}= \end{aligned}}

Hence all the angles bisectors \mathrm{\mathrm{PC}_1, \mathrm{PC}_2, \mathrm{PC}_3},... pass through a fixed point P which lies on the circle.

the circle.
