Q:
# Match the reasons with the statements in the proof if the last line of the proof would be 6. ∠1 and ∠7 are supplementary by definition. Given: s || t Prove: 1, 7 are supplementary 1. s||t Given 2. ∠5 and ∠7 are supplementary. Exterior sides in opposite rays. 3. m∠5 + m∠7 = 180° Definition of supplementary angles. 4. m∠1 = m∠5 Substitution 5. m∠1 + m∠7 = 180° If lines are ||, corresponding angles are equal.

Accepted Solution

A:

Answer:Given : s||tExterior sides in opposite rays : ∠5 and ∠7 are supplementaryDefinition of supplementary angles : m∠5 + m∠7 = 180°If lines are ||, corresponding angles are equal : m∠1 = m∠5Substitution : m∠1 + m∠7 = 180°
