Match the following items. complete the proof for theorem 3-13. 1. l||m given 2. m∠1 = m∠3 vertical angles are equal. 3. m∠2 = m∠3 substitution 4. m∠1 = m∠2 if lines are ||, corresponding angles are equal.

To find the proof of this theorem, you need to match column

a to column b.

The given are the following:

This would be column

a:

1. l||m

2.m∠1

= m∠3

3.m∠2

= m∠3

4.m∠1

= m∠2

This would be column b:

a. If lines are ||, corresponding angles are equal.

b. given

c. substitution

d. Vertical angles are equal.

The theorem is asking us to prove that m1 = m2. So the answers

would be:

1.      

Would be b because that is the given for the

theorem.

2.      

The answer is a.

3.      

The answer is d.

4.      

The answer is c.
