Filling out reasons and statements in geometry

Question

Given ∠1 ≅ ∠2, finish the proof that m∠1=m∠5.

Statement: ∠1 ≅ 2       Reason: 

Statement:  ∠2 ≅ 5      Reason:

Statement:                  Reason: Transitive property of angle congruence

Statement: m∠1=m∠5 Reason:

Answer 1

∠1≅∠2   Given

∠2≅∠5   opposite angles are congruent

∠1≅∠2, ∠2≅∠5, therefore ∠1≅∠5  Transitive...

m∠1=m∠5 congruent angles have the same (degree) measure
