Answer:
(d) Reflexive Property of ≅; SSS
Step-by-step explanation:
There are no angles involved in the proof, so the SAS claims do not apply.
__
The symmetric property says ...
if A ≅ B, then B ≅ A
The reflexive property says ...
A ≅ A
In this case, the reflexive property is the one being invoked in the statement ...
AC ≅ AC
That, together with the claims of line 3 concludes the claim that all three sides are congruent to their corresponding counterparts. Hence the SSS postulate applies.
