Question

2.

(02.05 MC)

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)

Answer:P’ = 1/3 P

reflection in the y-axis just changes the sign of all the x-values.

Since P” ≅ P’, and P’ is smaller than P, P” cannot be ≅ to P

It is, however, similar to P.

Answer:P’ = 1/3 P

Step-by-step explanation:Reflection in the y-axis just changes the sign of all the x-values. Since P” ≅ P’, and P’ is smaller than P, P” cannot be ≅ to P

. It is, however, similar to P.

Good luck!!
