Graph a triangle (LMN) and rotate it 180° around the origin to create triangle L′M′N′. Describe the transformation using words. Make sure you refer to the characteristics and the coordinates. Draw a line through points L and L′ and through M and M′. What do you notice about the lines you drew? Do you think you would notice the same characteristics if you drew another line through points N and N′? How do you know? Source StylesFormat
Welcome to questioncove o;
You didn't put a picture or anything, but I can tell you the basics When you rotate something 180 degrees around the origin, just change all the signs ex. (1,2) -> (-1,-2) (3,-1) -> (-3,1)
thx
it doesn't have a picture
How about the coordinate points you can't flip nothing..... lol
nope nothing, that's the question itself
OHH, it says graph 'a' triangle' So just choose 3 random coordinate points that can be made into a triangle
And then write down those coordinate, and then rotate it 180 degrees
uh where exactly can I graph it two
too*
Just graph it on desmos or something the question just wants description, not the actual thing, so, just graph 3 points on desmos, write them down, and then write down teh coordinates when it rotates 180 degrees
For example, i could do
And then, to rotate it 180 degrees, i flip all the signs and get
And then drawing a line, since i'm on desmos, i'll just do a linear equation do you see how they go through the origin
okay so I put these points
are they good?
Sure, any points that make a triangle works and so now flip all the signs
uh- how do I do dat two
twt*

The numbers stay the same, but positive turns negative, negative turns positive
ah I see
alright I did it
Post the image
is that right?
yep that's correct
alright so the draw the line part, how do I do dat?
Eh, this kind of just looks like how good you are with linear equations xd but since this is only about describing it, just say that each line goes through the two points and also the origin, you can look at my screenshot
oh okay let meh finish answering the first question
okay how do these answers look
1.For me the transformation was almost like flipping the traingle the opposite side, i put the coordinates (-4,5), (-2,1), and (-5,3) to make up the triangle, and in order to rotate it 180 degrees you have to switch the negatives with positives and positives with negatives making it (4,-5), (2,-1), and (5,-3). 2.Each line that i drew goes through the 2 points and also the origin, since when i drew it i can see how the lines pass by it.
yep, that's good
awesome! thank you soooo much! ill probably post like 3 more questions if that's okay?
altho the other half, the for point N, the answer is yes
uh, sure lol
