Please solve this both.

Dear Student,
The solution to your 2nd question is provided below:

 

given: AC and BD are perpendicular to the line segment AB.

and AD = BC.

TPT: CD bisects AB. i.e. OA = OB

proof: in the triangles OAD and OBC,

AD = BC (given)

∠OBC = ∠OAD = 90 deg

∠BOC = ∠AOD (opposite angles are equal)

therefore by AAS congruency:

thus by cpct, OA = OB.

thus CD bisects.

For remaining queries we request you to post complete and clear question in a seperate thread for rapid assistance from our experts.
Regards!
