Question

Great work so far! The police department now needs you to take the original triangle and reflect it. For this step, you will need to identify and label three points on the coordinate plane that are a reflection of the original triangle. Next, use the coordinates of your reflection to show that the two triangles are congruent by the ASA postulate. You can use the distance formula to show congruency for the sides. To show an angle is congruent to a corresponding angle, you can use slope or your compass and straightedge (Hint: Remember when you learned how to copy an angle?). You must show all wo

Answer 1

I already reflected it and my new coordinates are G' (-6,-3) C' (-6,3) W' (2,-3). They are abbreviated. I don't understand how to show the angles are congruent and how to show the congruency for the side.

Answer 2

@hanner_B_nanner

Answer 3

ok, take the coordinates from this one and plug them in as well.

Answer 4

Which ones? All?

Answer 5

I did A' and C'

Answer 6

or, C' and W'... lol i renamed my points :)

Answer 7

Is there any specific one i should do when doing this ?

Answer 8

I got 144 and 16

Answer 9

If i do C', Cand G, G' I get 144 for both

Answer 10

They all have to be equal though... The translation, reflection, and rotation. Goodness..lol, I'm confusing my own self! Let me SHOW you what I did, it might be easier than trying to explain it...

Answer 11

Well then that means i totally messed up on the first SSS part..

Answer 12

G' and G dont match up on SSS part x.x

Answer 13

UGH... I'm sorry :( I'm probably the worst "help" you've ever had... :(

Answer 14

Actually first time i have used this lol

Answer 15

I hate this flvs stuff anyways.... Wish i could go back to regular school lol

Answer 16

ruined the experience then... lol

Answer 17

yeah, ikr

Answer 18

if you want, you can just use what I gave you. If you want to make it different, you can just change the points, and that should give you a totally different answer.

Answer 19

What teacher did you have?

Answer 20

I don't think it would matter if i just sent it in and changed the name of the file.

Answer 21

O'Connor... i dislike that lady X( she's extremely picky. And yeah, that's fine!! :)

Answer 22

damn i have her too

Answer 23

hahaha!! too funny :D

Answer 24

Is that all correct? I think Im just gunna send it in i have been trying to do it for days

Answer 25

do you have geogebra? If so, the only thing you're gonna havta do to get 100% is graph them separate. So do the original triangle and translation on one, then the others... then send in the paper separate too. I got all the work right, she just wanted them all graphed by themselves for SOME reason. GRRR. If you dont I can do it real fast....

Answer 26

I have the program but it's dumb to use lol

Answer 27

sooo... yes, no, maybe? lol :)

Answer 28

I think i'm just gunna send it in and see what she says..... is her dba hard?

Answer 29

It's not too bad.You need to know what the x and y changes to in reflection, rotation, and y=x... Just go to the pages in the lesson and it will tell you. Umm... different ways of rotation...like 90counterclockwise, 90clockwise, 180... how to know if something is congruent, and you just say by using SSS, ASA, and the other one...whatever it's called I forget. lol. And that was pretty much it. I got a 100% on it && im terrible at explaining this stuff, as you can tell.

Answer 30

I can't wait to get out of this pellet but i have 5more courses to do

Answer 31

in mod 3 seriously take your time and read everything because it's really hard, && extrememly confusing. Yeah, Im doing 4 others and im waayy behind lol

Answer 32

this lady is the only one that gives me a hard time though X(

Answer 33

Can i copy and paste these seperate in geobra?

Answer 34

no, I dont think so. All you gotta do is click on the button up top that says polygon to do the two triangle. It's really fast and easy.

Answer 35

I usually do al these on paper x.x

Answer 36

ohhhh, not meee! lol if you wait just one sec ill do it for ya.

Answer 37

Coool

Answer 38

I just wanna get this pellet over with.. Move on to the next chapter lol
