∠GHI ≅ ∠DEF               - given
∠DEF ≅ ∠GHI               - symmetric property
∠ABC ≅ ∠GHI               - transitive property 
m∠ABC = m∠GHI          - definition of ≅ angles

Answer 2

Answer:

∠ABC ≅ ∠DEF- given

∠GHI ≅ ∠DEF- given

∠DEF ≅ ∠GHI- symmetric property

∠ABC ≅ ∠GHI- transitive property

m∠ABC = m∠GHI- definition of ≅ angles
