Which statement best represents the information that should be in the box labeled 1?

AB=BC

AB≅CA

BC≅CA

AB=CA

Answer 1

`Segement Congruence Postulate - Two segments are congruent if and only if they have the same length`

So we are given that `AB ≅ BC` so the two are of equal length soo `AB = BC`

Answer 2

We transit to `AB = BC` in which we are able to substitute.
