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.

sorry @Spring98 im a little confused on this.

- Spring98

@Loser66 plz i neeed help i will medal you

- Spring98

yes

- anonymous

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

- anonymous

dilated*

- Spring98

huh? That is not what the question is asking for. :(

@welshfella plzplzplzplzplz help me asap plzplzplzplz

- welshfella

the first part is a reflection in the y-axis
what do you think the second transformation is?

- welshfella

imagine the y-axis is a mirror - where would the image of ABCD be on the graph/

- welshfella

this is an example of a line reflected in y-axis

- welshfella

note that the points are 'reversed'

- Spring98

yes i know so what happened with the one were talking about here did it get reflected then translated?

- welshfella

In your diagram where would the point B' be?

- welshfella

yes

- welshfella

in what direction and how many units did the image get translated?

- Spring98

it is 2,-2

- welshfella

B' is (2,-2) yes but how exactly did it get there?

- welshfella

madison has given you the right answer but you need to explain it in more detail.

- Spring98

it got reflected and then translated i think

- welshfella

yes exactly
but in what did it get reflected and what is direction and magnitude of the translation?

- Spring98

im not sure what you are talking about

- welshfella

the question also asks you to write the coordinates of the figure after each transformation.

- Spring98

yes so do i write down the A'B'C'D' coordinates?

- welshfella

deal with the reflection first
- in what axis is it reflected and what are the coordinates of the 4 points?

- Spring98

umm. it reflects over the y- axis right?

- welshfella

yes

- welshfella

and what are the new coordinates of A, B C and D?

- 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

No you need to write the coordinates after the retlection
eg A (4,-4) goes to A' ( 4,4)

- Spring98

ohhhhh sorry i will do that again?

- welshfella

ok

- 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

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

|dw:1444334292983:dw|

- welshfella

the questions asks you to write the coordinates of each point after EACH transformation.

- Spring98

yes so are my coordinates right?

- welshfella

the coordinates are correct for the FINAL IMAGE - but you need to write the ones for the intermediate image as well.

- Spring98

? huh?

- Spring98

can you explain this to me plz

- Spring98

can you also use words like for a kindergardener plz im confused all over agian
