m∠ABC = m∠GHI      transitive property of congruence

Step-by-step explanation:

The transitive property of congruence states that two objects that are congruent to a third object are also congruent to each other

In this case, ∠ABC is congruent to ∠DEF; ∠DEF is also congruent to ∠GHI, then ∠ABC is congruent to ∠GHI, which means that the measure of these angles (m∠ABC and m∠GHI) are equal
