Triangle PQR is transformed to triangle P'Q'R'. Triangle PQR has vertices P(8,0), 2(6,2), and R(-2,-4). Triangle P'Q'R' has vertices P'(4,0), Q'(3, 1), and R'(-1, -2).
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 PQ"R" congruent? Explain your answer. (2 points)
