Question

Please help!

Triangle PQR is transformed to triangle P'Q'R'. Triangle PQR has vertices P(8, 0), Q(6, 2), and R(−2, −4). Triangle P'Q'R' has vertices P'(4, 0), Q'(3, 1), and R'(−1, −2).

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)

Answer 1

Part one:

Print this blank grid, or copy and paste it in a painting tool, and accurately/correctly mark PQR and P'Q'R'


Hint: Make sure you start with PQR, hence that is the pre-image and the shape BEING dilated. P'Q'R' is the shape after being dilated/transformed.


To correctly graph the points TIP:

Make sure, you go across the X axis, then the Y. You run, before you jump.

Answer 2

When you do that, tag me so we could do and finish part A and B. It is indeed simpler than you think. @Nikki_Skellington

Answer 3

ok, thank you.

Answer 4

done @MissSmartiez

Answer 5

Can you send me the doc or work so we could go from it there?

Answer 6

i think i did it wrong :/
