Match the reasons with the statements.
complete the proof for theorem 3-16 above, with the information given.
given:
m1 = m2
prove:
l | | m
plan:
same as theorem 3-15
1. m∠1 = m∠2 given
2. m∠1 = m∠3 substitution
3. m∠2 = m∠3 if corresponding angles are equal, then lines are parallel.
4. l||m vertical angles are equal.
