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!
