diana's proof
statement justification
∠1 + ∠2 = 180° definition of supplementary angles
∠1 + ∠4 = 180° definition of supplementary angles
∠1 + ∠2 = ∠1 + ∠4 transitive property of equality
joby's proof
statement justification
∠2 = ∠4 vertical angles are congruent.
∠1 = ∠3 vertical angles are congruent.
vertical angles are congruent. vertical angle theorem
