To complete the proof that consecutive interior angles are supplementary, we need to find a statement and reason that connects the equation \( m∡A = m∡E \) with the given information.
Here's the completed proof with the appropriate statement and reason filled in:
Given: \( n \parallel m \)
Statements | Reasons --------------------------------------|----------------------------------------
- \( m∡A + m∡C = 180^\circ \) | Linear pairs are supplementary
- \( m∡A = m∡E \) | Corresponding Angles Postulate
- \( m∡E + m∡C = 180^\circ \) | Substitution
- ∠E and ∠C are supplementary | Definition of Supplementary Angles
So the correct response to fill in the blank is:
Corresponding Angles Postulate
