PLEASE HELP!

OpenStudy (tkhunny):

Please SHOW your work. Okay, not subtracted 4 from each x-value and added 3 to each y-value? Why would you NOT connect the vertices? Don't we want a triangle? Did we do anything to increase or decrease the length of any side?

OpenStudy (anonymous):

The new coordinates would be S' is (-2, 4), T' is (-2,6) and U' is (-4,2)

OpenStudy (tkhunny):

Stop tagging people and start showing your work. How do the two triangles relate to each other? Are there SIMILARities? Are there differences?

OpenStudy (anonymous):

@tkhunny I'm tagging people because I need an explanation. I can't show my work if I don't know how to solve it in the first place /: I'm trying to see if there are similarities and differences

OpenStudy (tkhunny):

That's incorrect. I know you have SOMETHING or you would not have performed the translation well. Now is the time for you to think on geometry. If you pick up a triangle and drop it somewhere else, what happened to the shape of the triangle?

OpenStudy (anonymous):

All the question is asking me is to show the new coordinates and identify characteristics I would find if the corresponding vertices were connected with line segments

OpenStudy (anonymous):

Well, the triangle would most likely change, or translate right? I'm supposing the same occurs in this case @tkhunny

OpenStudy (tkhunny):

Just pick it up and put it down somewhere else. Why would it change?

OpenStudy (anonymous):

It would change because it was moved, it isn't in the same place it was before @tkhunny

OpenStudy (tkhunny):

That is not correct. That doesn't change the triangle. That changes only the triangle's location. If you drive a car from New York to Chicago, do you then have a different car? Or is it now a different car since it is a Chicago-car, rather than a New-York-car?

OpenStudy (anonymous):

No, it's the same car, just in a different place @tkhunny

OpenStudy (tkhunny):

There you go. Since we didn't twist, stretch, or even rotate this triangle, or poke holes in it or anything, wouldn't the two triangles be congruent?

OpenStudy (anonymous):

Yes, they would be congruent! But what does this have to do with the characteristics if the corresponding vertices were connected with line segments? @tkhunny

OpenStudy (anonymous):

If the vertices were connected to the line segments, wouldn't the characteristics remain the same? @tkhunny

OpenStudy (tkhunny):

"Describe what characteristics you would find if the corresponding vertices were connected with line segments" It is not asking about characteristics of vertices. It is telling you to construct a new triangle, given the vertices. It's about triangles, not vertices. The vertices are just to tell us where it is.

OpenStudy (tkhunny):

Vertices are a bit difficult to characterize. They are just points. The definition of a point is accepted axiomatically in most early cases of your journey through mathematics.

OpenStudy (anonymous):

I have learned about points and vertices. So in this case the new coordinates to the triangle has the same lengths and angles but is offset from the original? @tkhunny

OpenStudy (anonymous):

@tkhunny Thank you for your guidance but I just submitted it. I tried my best to solve it on my own.

OpenStudy (howard-wolowitz):

It might shift imo! depending on how high it is when you drop it

OpenStudy (tkhunny):

No, it's a triangle. It's not subject to physical forces. They are just points and line segments.

OpenStudy (howard-wolowitz):

alright fine, your right
