Triangle UVW is shown below with line AB passing through points A and B:

Triangle UVW is shown with point A lying on side UV and point B lying on side UW. Line AB is perpendicular to side UW.

If triangle UVW is dilated about the center of the triangle to create triangle U'V'W', what can you conclude about segments AB and A'B'?

Question

Triangle UVW is shown below with line AB passing through points A and B:

Triangle UVW is shown with point A lying on side UV and point B lying on side UW. Line AB is perpendicular to side UW.

If triangle UVW is dilated about the center of the triangle to create triangle U'V'W', what can you conclude about segments AB and A'B'?

anonymous · Answer

Line A'B' contains point V.

 Segments A'B' and U'W' are parallel.

 Lines AB and A'B' are parallel.

 Lines AB and A'B' are perpendicular.

Wow, how do I get mentioned with such respected users? :o
Let me try to graphically represent this problem so you can better understand it.

I think your correct

dangerousjesse · Answer

Please link any photos or diagrams :)

@dolphin1998 what was his/her guess?

malcolmmcswain · Answer

"Triangle UVW is shown below"
Yes, we need to see the triangle.

dangerousjesse · Answer

If you can't download it directly, just post a screenshot

anonymous · Answer

My guess is A, and how do I screenshot?

dangerousjesse · Answer

There should be a button that says "prt sc" on the top of your keyboard :) Press that, open paint, press ctrl+v (or apple+v) and save, then attach the file here.

Thank you ^_^

anonymous · Answer

Yeah, do you think you are able to help?

malcolmmcswain · Answer

Well, for one thing, you cannot conclude A. This is because we don't know the dilation factor of the transformation.

anonymous · Answer

Oh, true. Sory. I dont understand the question very well

malcolmmcswain · Answer

Does that help?

dangerousjesse · Answer

Where does it say AB is moved during the dilation?

anonymous · Answer

I think it might be C or D, With his picture shown.

dangerousjesse · Answer

I mean, logically, that's the only possible answer.. but this question is very poorly written.

anonymous · Answer

I agree. But what is the Answer, C?

dangerousjesse · Answer

I believe so. D could only be true if the triangle were rotated and dilated, A cannot be true based on what we've been told, and B cannot be true unless the triangle itself is rotated about any one vertex.

anonymous · Answer

Can you HELP with one more question? It is sim to the question above

dangerousjesse · Answer

Of course.

anonymous · Answer

Want me to make a new post? or may i post it on here?

dangerousjesse · Answer

Either way is fine by me.

Oh, wait, this is an exam?
