Q:
# Complete the proof for theorem 3-13. 1. l||m if lines are ||, corresponding angles are equal. 2. m∠1 = m∠3 vertical angles are equal. 3. m∠2 = m∠3 given 4. m∠1 = m∠2 substitution

Accepted Solution

A:

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.

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.
