Prove that if two angles are complementary to the same angle then they are equal in measure.

1. Subtraction property of equality
2. Given
3. Definition of complementary
4. Substitution
∠1 is complementary to ∠2 and ∠3 is complementary to ∠2.
m∠1 + m∠2 = 90 and m∠3 + m∠2 = 90
m∠1 + m∠2 = m∠3 + m∠2
m∠1 = m∠3
