Part A: Write the sequence of transformations that changes figure ABCD to figure A'B'C'D'. Explain your answer and write the coordinates of the figure obtained after each transformation. Part B: Are the two figures congruent? Explain your answer.

Part A: Reflection and translation Part B: yes it was not dialated

the first part is a reflection in the y-axis what do you think the second transformation is?
welshfella
  • welshfella
imagine the y-axis is a mirror - where would the image of ABCD be on the graph/
welshfella
  • welshfella
this is an example of a line reflected in y-axis |dw:1444332587762:dw|
welshfella
  • welshfella
note that the points are 'reversed'
Spring98
  • Spring98
yes i know so what happened with the one were talking about here did it get reflected then translated?
welshfella
  • welshfella
In your diagram where would the point B' be?
welshfella
  • welshfella
yes
welshfella
  • welshfella
in what direction and how many units did the image get translated?
Spring98
  • Spring98
it is 2,-2
welshfella
  • welshfella
B' is (2,-2) yes but how exactly did it get there?
welshfella
  • welshfella
madison has given you the right answer but you need to explain it in more detail.
Spring98
  • Spring98
it got reflected and then translated i think
welshfella
  • welshfella
yes exactly but in what did it get reflected and what is direction and magnitude of the translation?
Spring98
  • Spring98
im not sure what you are talking about
welshfella
  • welshfella
the question also asks you to write the coordinates of the figure after each transformation.
Spring98
  • Spring98
yes so do i write down the A'B'C'D' coordinates?
welshfella
  • welshfella
deal with the reflection first - in what axis is it reflected and what are the coordinates of the 4 points?
Spring98
  • Spring98
umm. it reflects over the y- axis right?
welshfella
  • welshfella
yes
welshfella
  • welshfella
and what are the new coordinates of A, B C and D?
Spring98
  • Spring98
ok so know i have to right down the coordinates, which are A'(4,0) B'(2,-2) C'(2,-5) and D'(4,-3) right?
welshfella
  • welshfella
No you need to write the coordinates after the retlection eg A (4,-4) goes to A' ( 4,4)
Spring98
  • Spring98
ohhhhh sorry i will do that again?
welshfella
  • welshfella
ok
Spring98
  • Spring98
A(-4,4) to A'(4,0), B(-2,2) to B'(2,-2), C(-2,-1) to C'(2,-5), D(-4,1) to D'(4,-3). Did i do this right @welshfella ?
welshfella
  • welshfella
No you have not written to coordinates of the image formed after the first transformation which was the reflection you have missed that part out
welshfella
  • welshfella
|dw:1444334292983:dw|
welshfella
  • welshfella
the questions asks you to write the coordinates of each point after EACH transformation.
Spring98
  • Spring98
yes so are my coordinates right?
welshfella
  • welshfella
the coordinates are correct for the FINAL IMAGE - but you need to write the ones for the intermediate image as well.
Spring98
  • Spring98
? huh?
Spring98
  • Spring98
can you explain this to me plz
Spring98
  • Spring98
can you also use words like for a kindergardener plz im confused all over agian
