Answer: Third option is correct.
Explanation:
Since we have given that
Transitive property of equality defines that
if a=b, b=c
then, a=c
So, According to question we have
∠A = ∠B and ∠B = ∠C
then ∠A = ∠C
In other options,
For instance, in first option, there is a transposition not transitivity,
in second option and in fourth option , there is just left or right position shift
So, Third option is correct.
