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.

1. m∠1 = m∠2
a:Substitution
2. m∠1 = m∠3
B:If corresponding angles are equal, then lines are parallel.
3. m∠2 = m∠3
c:Vertical angles are equal.
4. l||m
D:Given

Answer 1

Answer:

Given: m1 = m2

If corresponding angles equal, lines are parallel: m2 = m3

Vertical angles are equal: l||m

Substitution: m1 = m3
