Triangle PQR is transformed to triangle P'Q'R'. Triangle PQR has vertices P(3, −6), Q(0, 9), and R(−3, 0). Triangle P'Q'R' has vertices P'(1, −2), Q'(0, 3), and R'(−1, 0).
Plot triangles PQR and P'Q'R' on your own coordinate grid.
Part A: What is the scale factor of the dilation that transforms triangle PQR to triangle P'Q'R'? Explain your answer. (4 points)
Part B: Write the coordinates of triangle P"Q"R" obtained after P'Q'R' is reflected about the y-axis. (4 points)
Part C: Are the two triangles PQR and P''Q''R'' congruent? Explain your answer. (2 points)

What grade is this?

- anonymous

8th

- anonymous

._. and she left

- Destinyyyy

Oh that explains why I recognize it but don't remember how to solve it. Sorry that was like 6 years ago

- anonymous

O^O
- Oh

- triciaal

start by using the "draw" to sketch the figures

- Destinyyyy

Id help if I could remember.

- triciaal

the dilation factor is the ratio of the corresponding lengths
this means you have to find the length for example of PQ and P'Q' then set as ratio

- anonymous

how do i do tht

- triciaal

to reflect about the y-axis the x coordinate will become -x and the y coordinate will stay the same

- anonymous

(-0, 9) and so on ??

|dw:1440022908017:dw|
the blue dot is the point (2, 4) when reflected across the y-axis it will now be at the green spot. it moves the same distance in the opposite direction from the "mirror" y-axis. and at the same height/y value 4 it is now at (-2, 4)

- triciaal

you need to label the points, axis and on the same grid put P'Q'R'

- triciaal

since you don't need my help anymore I will leave.

ok
