Question

I got this question wrong on a test yesterday. I does not count as a grade any more just wounder how its supposed to be done.
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.

Part B: Write the coordinates of triangle P"Q"R" obtained after P'Q'R' is reflected about the y-axis.

Part C: Are the two triangles PQR and P''Q''R'' congruent? Explain your answer.

Answer 2

look for your answer there ~

Answer 3

I cant read all that ill fall a sleep. so Ill try to figure it out.
This is my answer I got now let me know if its right....
Triangle P' Q' R' is half the size of the original triangle. The scale factor is 1/3.
Part B: P'(1, −2), Q'(0, 3), and R'(−1, 0).
Part C: No, the two triangles are not congruent.
When two triangles are congruent they are the same shape, and size. But when dilation is preformed on an triangle the triangle size changes which means the triangle is not the same size as the original so its not congruent but it is similar.

Am I right or do I have it wrong
