Respuesta :

b. the symmetric property

Answer:

The property of equality that justifies this statement: if l=m , then m=l  is:

                     b. symmetric property

Step-by-step explanation:

We know that the symmetric property of relations states that if a is related to b by any relation R i.e. a R b

then b is also related to a by the same relation i.e.  b R a

Hence, we have a relation as a equality relation,

i.e.   a R b means   a=b

Hence, symmetric property states that

b R a that means   b=a

              Hence, the answer is:

                 Option: b
