What is the missing justification?
frutty [35]

Answer:

Transitive property

Step-by-step explanation:

Given

See attachment

Required

The missing property?

In step 1, we have:

\angle A \cong \angle B,\ \angle C \cong \angle B

Transitive property states that:

If a = b and b = c

Then a = c

Similarly:

If \angle A \cong \angle B and \angle C \cong \angle B

Then  \angle A \cong \angle C --- step 3

<em>Hence, we can conclude that the transitive property is the missing justification</em>
