Answer 1

Answer:

BO=AO

Step-by-step explanation:

Given:

AD=BC (1st equation)

AD perpendicular to AB , i.e. angle OAD= 90°

BC perpendicular to AB , i.e. angle OBC=90°

TO PROVE: CD bisects AB i.e. OA=OB

PROOF:

Since,

Line CD & AB intersect

Angle AOD =Angle BOC (vertically opposite angles) -2nd equation

In ∆BOC and ∆AOD,

Angle BOC = Angle AOD ( from equation 2)

Angle CBO = Angle DAO (both angles are 90°)

BC=AD (from equation 1)

Therefore, ∆BOC Congruence to ∆AOD (AAS Congruence rule)

therefore, BO=AO

Hence porved
