Given: m∠1 + m∠2 = 90 Prove: m∠3 = 90

∠1+∠2≅<3, <1 , <1 ≅ <3, ∠1m + m∠2 = m∠3, the sum of ∠1 and ∠2, m∠3 = 90

∠3 forms a vertical angle--------------- , which means ---------------------- .

So --------------- by the definition of congruent angles. Since m∠1 + m∠2 = 90 is given,---------- by the transitive property of equality.
