Answer:

$\color{red}\huge{\underline{\underline{\mathfrak{Answer}}}}$

In the figure there are two triangles which are triangle BCO and triangle ADO.

Now,

In both the triangles

Angle OBC=Angle OAD [each are of 90°(given)]

AD=BC [Given]

Angle BCO=Angle ADO [Alternate angles as BC//AD]

So, triangle BCO is congruent to triangle ADO

Hence, AO=OB [Corresponding parts of congruent triangles]

Hence, CD bisects AB
