Answer:

\Large\underline{\underline{\sf{ \color{magenta}{\qquad Given \qquad}  }}}

In △s, ABD and ACD,

AD=AD (Common)

AB=AC (Given, ABC is an isosceles triangle)

DB=DC (Given, DBC is an isosceles triangle)

Thus, △ABD≅△ACD (SSS postulate)

Hence, PB=PC (By cpct)

and, ∠APB=∠APC=x (By cpct)

Now, ∠APB+∠APC=180

x+x=180

x=90°

Thus, AP is perpendicular bisector of BC
