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)

I'm sorry if its not right i tried my best. have a great day!!

Step-by-step explanation:

Part A: What is the scale factor of the dilation that transforms triangle PQR to triangle P'Q'R' the scale factor dilation is 

Part B: The new coordinates of triangle P"Q"R" is p is at (1, -2), (0,-3), (1,0).

Part C: No, the two triangles are not congruent they are the same shape but not the same size. The Triangle P'Q'R' is much smaller than the triangle PQR.

pay attention in your classes and concentrate the best thing you can do to raise your test scores is to pay attention when you're supposed to be learning the material: in class!

take good notes.

do your homework.

use mnemonics and other tricks.

do practice tests.
