Answer:
ΔADB~ΔCDB; SAS~
Step-by-step explanation:
Due to the tick marks on AD and DC, we know that those sides are congruent
We also know that the angle D is congruent due to the marks
As they share line BD, that side is also congruent.
This means that we have a side, an angle, and another side.
This leaves us with the last two options
The only difference between them is what angle corresponds to which
In the case of this triangle, A and C correspond with each other and B and D are shared. This means we are looking for when the locations of A and C, and B and D are matched
This would mean that the 4th option
ΔADB~ΔCDB; SAS~
