Question

In the given figure, if AC = BD the prove that AB = CD​

Answer 1

Answer:

$answer$

AC = BD

AB + BC = BC + CD

AB = BC + CD - BC

AB = CD

Answer 2

Answer:

to prove : AB = CD

given : AC = BD

proof :

we have to prove that AB = CD. So, we have to somehow relate this to the given relation AC = BD.

from the figure, we can say that

AB = AC-BC and CD = BD-BC

and we know that, AC = BD

then, AC-BC = BD-BC

i.e, AB = CD.

hence, proved.
