# Triangle PQR is transformed to triangle PQR. Triangle PQR

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