Given: ΔABC ≅ ΔFDE What is the length of Segment line DE rounded to the nearest tenth?
@Vocaloid Helpz
BC = DE judging by our formula so you would use the distance formula to find BC
|dw:1504839436323:dw|
So the length f Bc is the same as DE?
yes
So I plug it into that formula?
yes
Ok
3.2?
good, that's your answer
Oh okz
I have two more left
Which could be coordinates of D'O'G' after the reflection?
does it say what the reflection is?
Well this ones multiple choice if that helps but thats it
D'=(0,0), O'=(−1,−2), G'=(1,4) D'=(0,0), O'=(−1,−2), G'=(1,−4) D'=(0,0), O'=(−2, 1), G'=(−1, −4) D'=(0,0), O'=(−1,2), G'=(1,4)
so I believe it would be the last one since it would be a reflection across y (the x-coordinates get multiplied by -1)
the other ones would change the shape of the triangle
if you're given a problem like this in the future, just make a quick sketch of the coordinates to see which ones are actually reflections and which ones change the shape
Ok Ill belive you and your long explanations :p
Ok theres one more then you are done interacting with me lmao
What coordinate for F would make triangle ABC and triangle DEF congruent?
(−3,−3) (−3,−2) (−2,−3) (−2,−2)
BA and DE have to be equal so point F must correspond to point C since point C is 1 unit up and 3 units to the right from B, we do a similar transformation to find F
so: go from point D, go 1 unit to the left and 3 units down to get F let me know what you get
Ok
-3,-2?
almost
(-2,-3)
Man I always get the x and y axis confused srry
Oh wait I got the answer to one could you check it sorry
What additional information would you need to prove that ΔABC ≅ ΔDEF by SSS?
segment AC ≅ segment DF segment AC ≅ segment FD segment AF ≅ segment CD segment FA ≅ segment CD
I got A^
yep good
Really ok
Thanks Vocaloid Ill tell you tom if I aced it I still gotta do a writing part so thanks again gn!
