Triangle PQR is transformed to triangle P'Q'R'. Triangle PQR has vertices P(3, β6), Q(0, 9), and R(β3, 0). Triangle P'Q'R' has vertices P'(1, β2), Q'(0, 3), and R'(β1, 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)
