Answer:
The answer is below
Step-by-step explanation:
The transitive property of equality states that if if two different quantities are equal to a third quantity then the two quantities are equal to each other. The property is illustrated as follows:
For a ,b, c, if a = b, a = c, then b = c (transitive propety oif equality).
Therefore given that:
∠ABC ≅ ∠DEF and ∠GHI ≅ ∠DEF: hence we can conclude that:
m∠ABC = m∠DEF (transitive property of equality)
