Match the reasons with the statements in the proof if the last line of the proof is:
6. ∠3 and ∠5 are supplementary because of the definition of supplementary.
given:
s | | t
prove:
3, 5 are supplementary
1. s||t definition of supplementary
2. ∠1 and ∠3 are supplementary exterior sides in opposite rays
3. m∠1 + m∠3 = 180° given
4. m∠1 = m∠5 substitution
5. m∠5 + m∠3 = 180° if lines are ||, corresponding angles are equal
