Do you have a picture that I can look at to help you out? 
I would say that Line AB = YU which means that Line BA = Line UY but I can't be sure because I can't see it.

Answer:

The symmetric property of equality lets you say that if AB=YU,then

                        YU=AB

Step-by-step explanation:

Let us consider a set A and a  relation R.

Here R is a relation of equality.

Let us consider two elements a, b belong to set A.

Then the symmetric property states that:

If a=b then b=a

( i.e. if a is related to b by the relation of equality then b will also be related to a by the same relation)

  Here we have: a= AB

and b= YU

Hence, if AB=YU then by the property of symmetry we have:

          YU=AB
