Question

ABCD is rectangle. BD is the diagonal of the rectangle. Which all congruence criterion can be used to show ABD is congruent to DCB?

Answer 1

*AB=DC
*AD=BC
*BD=BD
so ABD is congruent to DCB(SSS criterion)

Answer 2

Answer:

A= C ( 90 degree )

Hypotenuse BD= Hypotenuse DB

BC= BC ( common )

Hence,RHS citerion is used

But, SSS citerion is also used here as

BC=AD ( given )

AB=DC ( given )

BD=BD ( common )
