Question

Huy is working on a proof that consecutive interior angles are supplementary.

Statement Reason
1. m∠A+m∠C=180°
Linear pairs are supplementary
2. m∠A=m∠E

3. m∠E+m∠C=180°
Substitution
4. ∠E
and ∠C
are supplementary Definition of supplementary angles

What is the missing reason in the proof?
