In excercises 13 and 14, the vertices of triangle ABC are A(-4,4) B(-1,2) and C(-4, 1). Find the vertices of triangle A"B"C" after a composition of transformations in the order they are listed. 13. Translation: (x,y)----->(x+3, y-2) Translation: (x,y)----->(x-1, y+4) 14. Translation: (x,y)----->(x+2, y+1) Reflection: In the x-axis.

13. Translation: (x,y)----->(x+3, y-2) Translation: (x,y)----->(x-1, y+4) these two can be combined into one : (x,y)----->(x+2, y+2)

you just need to move the original triangle to right by 2 units, and up by 2 units. add 2 to all coordinates of vertices

  • Ammarah
wait i dont get it...can u just plug in each of the vertices into the x=3, y-2 and x-1, y+4?
Ammarah
  • Ammarah
so like the first transformation would be A(-1,2) B(2,0) C(-1,-1)>? idk what it means by the order they are listeedd...
ganeshie8
  • ganeshie8
thats correct after first transformation. do the second transformation also, then il tell what A B C are :)
Ammarah
  • Ammarah
and the second one would be A(-5,8)B(-2,6) C(-5,5)
ganeshie8
  • ganeshie8
nope, you need to do second one on the first one
ganeshie8
  • ganeshie8
take what u got after first transformation, and do second transformation on that
Ammarah
  • Ammarah
ohhkay so thats it? i mean is that all u have to do?
ganeshie8
  • ganeshie8
yes !
Ammarah
  • Ammarah
Okay so my final answer would be: A(-1,2) B(2,0) C(-1,-1) A(0,1) B(1,-1) C(0,3)
Ammarah
  • Ammarah
okay what about number 14...
ganeshie8
  • ganeshie8
wait
ganeshie8
  • ganeshie8
2nd transformation u did wrong
ganeshie8
  • ganeshie8
Okay so my final answer would be: A(-1,2) B(2,0) C(-1,-1) A(-1-1,2+4) B(2-1,0+4) C(-1-1,-1+4) A(-2, 6) B(1, 4) C(-2, 3)

ohkay for number 14.....so i did the same thing with the translation and i got A(-2,5)B (1,3) C(-2,2) but how do u find the reflection in the x-axis?
ganeshie8
  • ganeshie8
thats correct after first transformation
ganeshie8
  • ganeshie8
reflection in x axis : flip the y-coordinate sign
ganeshie8
  • ganeshie8
(x, y) ---> (x, -y)
Ammarah
  • Ammarah
so A(-2,-5)B(1,-3)C(-2,-2)
ganeshie8
  • ganeshie8
thats right !
ganeshie8
  • ganeshie8
good work :)
