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.

HOPE THIS HELPS

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
