Medals for help please.

OpenStudy (anonymous):

Which lines are parallel if m<4=m<5?

OpenStudy (watergirl):

m

OpenStudy (fibonaccichick666):

neither of them are correct. So can you tell me what alternate interior angles are?

OpenStudy (fibonaccichick666):

no... it's not

OpenStudy (anonymous):

Woouldn't the alternate interior be 3 and 6?

OpenStudy (fibonaccichick666):

Those are, can you tell me the other pair?

OpenStudy (anonymous):

1 and 4?

OpenStudy (anonymous):

Or is it 2 and 4

OpenStudy (fibonaccichick666):

no 1 and 4 are called vertical angles

OpenStudy (fibonaccichick666):

Sousa you are incorrect

OpenStudy (fibonaccichick666):

5th postulate

OpenStudy (anonymous):

2 and 4

OpenStudy (fibonaccichick666):

2 and 4 are supplementary

OpenStudy (anonymous):

THe last i can think of is 2 and 8.

OpenStudy (fibonaccichick666):

2 and 8 would be alternate interior iff l and m were parallel

OpenStudy (fibonaccichick666):

what angles are you given? Are they alternate interior?

OpenStudy (anonymous):

i think so.. is <4 and <5 parallel to <2 and <8

OpenStudy (fibonaccichick666):

no, angles can't be parallel. Only lines can

OpenStudy (fibonaccichick666):

Ok forget everything we just did. Start from the beginning, what are we given to start?

OpenStudy (anonymous):

Just that picture.. i have to write out what its parallel too.

OpenStudy (fibonaccichick666):

First, are you given the measure of any angles?

OpenStudy (anonymous):

No sadly.

OpenStudy (fibonaccichick666):

Go back and look, you are given one more piece of information.

OpenStudy (anonymous):

Which lines are parallel if m<4=m<5? Justify your answer.

OpenStudy (anonymous):

thats it

OpenStudy (fibonaccichick666):

Now you are given the picture and? The measure of which angles?

OpenStudy (fibonaccichick666):

reread the question, you are given 2 angles

OpenStudy (anonymous):

YEAH. the two angles <4 and <5. thats it. Nothing else is on the question.

OpenStudy (fibonaccichick666):

But that's all you need

OpenStudy (fibonaccichick666):

What do you know about angle 4 and angle 5?

OpenStudy (anonymous):

Are they interior angles.

OpenStudy (fibonaccichick666):

They are

OpenStudy (fibonaccichick666):

specifically, what type?

OpenStudy (fibonaccichick666):

_______ interior angles

OpenStudy (anonymous):

Vertical interior angles?

OpenStudy (fibonaccichick666):

no, hint* I asked you before about this type of angle

OpenStudy (fibonaccichick666):

*type of angle pair

OpenStudy (anonymous):

Alternate

OpenStudy (fibonaccichick666):

yes, so what do you know about alternate interior angles?

OpenStudy (fibonaccichick666):

when are they the same?

OpenStudy (anonymous):

im not sure..

OpenStudy (fibonaccichick666):

okay read this: http://www.mathsisfun.com/geometry/alternate-interior-angles.html

OpenStudy (anonymous):

i just dont understand still.

OpenStudy (fibonaccichick666):

read the parallel lines section again

OpenStudy (fibonaccichick666):

I'll find another

OpenStudy (fibonaccichick666):

http://www.mathwords.com/a/alternate_interior_angles.htm

OpenStudy (anonymous):

In that would 7 and 2 be the paralell?

OpenStudy (fibonaccichick666):

angles can't be parallel only lines can

OpenStudy (anonymous):

The transveral line

OpenStudy (fibonaccichick666):

What about the transversal line?
