Answer 1

HEYA MATE, HERE IS UR ANSWER ___________________

Given - AD=BC
2)angle A =Angle B ( each 90 )


To prove - AO =BO ie CD bisects AB

Proof -In triangle AOD and Triangle BOC

AD=BC (given )

Angle A =angle B (Given )

Angle AOD=angle BOC ( VOA)

Therefore Triangle AOD congruent triangle BOC ( AAS)

Hence, AO =BO ( by CPCT)

Hence Proved

Answer 2

In triangle AOD and triangle BOC
angle A=angle B(90°)
angleAOD=angleBOD(vertically opp.)
AD=BC
By AAS congruence rule
triangle AOD congruent triangle BOC
So,CO=DO(CPCT)
it implies AB bisects CD
