Please help!!!

OpenStudy (yanasidlinskiy):

@iambatman @SolomonZelman either one of you..Can you check to see if I'm right on the first one and help me with the second question??

OpenStudy (solomonzelman):

Attachment isn't working for me. iambatman will help. (Probably)

OpenStudy (yanasidlinskiy):

uuuu...Really?? Download it.......It should...cuz it works for me..

OpenStudy (anonymous):

Can you help me on an algebra problem PLEASEE!??

OpenStudy (anteater):

You have questions about the geometry proof?

OpenStudy (anteater):

Yes, your answers are correct for the two-column proof. :)

OpenStudy (anteater):

You have an algebra question as well?

OpenStudy (yanasidlinskiy):

For the first one..Is it correct?

OpenStudy (anteater):

Yes :)

OpenStudy (yanasidlinskiy):

What about the second one.. Can you help me??

OpenStudy (anteater):

And for the second one, if you were to extend the line that connects U and Y

OpenStudy (anteater):

You will note that it is parallel to the line segment that forms the base of that triangle

OpenStudy (anteater):

and line segment VT would be a transversal

OpenStudy (anteater):

So what relationship would angle T have to angle VUY?

OpenStudy (anteater):

or angle U, if you would rather call it that. :)

OpenStudy (yanasidlinskiy):

Hang on..Let me get my book...I want to answer it first..

OpenStudy (anteater):

Certainly

OpenStudy (anteater):

I enlarged and zoomed in on that part of the drawing, so if it will help I can post that here.

OpenStudy (yanasidlinskiy):

i don't know..I give up..If I'm not mistaking...I have no clue......And yes..Post that here...

OpenStudy (anteater):

Just a moment please :)

OpenStudy (anteater):

I think that may better demonstrate the relationship

OpenStudy (anteater):

And you had something similar in your previous problem.

OpenStudy (yanasidlinskiy):

Suplementary? Let me check..

OpenStudy (yanasidlinskiy):

I meant corresponding..yes??

OpenStudy (anteater):

Yes!

OpenStudy (yanasidlinskiy):

Ok. So that would be the first one right?

OpenStudy (anteater):

So sometimes when they give you a drawing of a figure, it can help to extend line segments to clarify the relationship between angles and lines.

OpenStudy (anteater):

Yes, that should be the answer to the first one.

OpenStudy (yanasidlinskiy):

Ok..Thanx Sooooo much!!!:) What about the second one?

OpenStudy (yanasidlinskiy):

@anteater ??

OpenStudy (anteater):

No problem! Looking at it now. :)

OpenStudy (anteater):

Sorry - I thought I had posted that.

OpenStudy (yanasidlinskiy):

..Its fine..I thought you were gone for a sec...

OpenStudy (yanasidlinskiy):

Can you draw it out like you did for me with the one above? Cuz I hahve no clue...

OpenStudy (anteater):

Still thinking on it. Since YU and XW are parallel, then UW must be congruent to YX, and UWXY is a parallelogram. I am trying to see where to go from there.

OpenStudy (yanasidlinskiy):

Aww....Ok...

OpenStudy (anteater):

Oh! Ok :)

OpenStudy (anteater):

Another drawing

OpenStudy (anteater):

|dw:1401741404323:dw|

OpenStudy (anteater):

So you have a triangle where two angles are equal (an isosceles triangle).

OpenStudy (anteater):

And so if those two angles of that triangle are congruent, what does that tell you about the sides opposite those angles?

OpenStudy (anteater):

I don't know why I looked at the parallelogram before - not necessary.

OpenStudy (anteater):

But we do have an isosceles triangle.
