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 yaxis. (4 points)
Part C: Are the two triangles PQR and P''Q''R'' congruent? Explain your answer. (2 points)

Best ResponseYou've already chosen the best response.0a) scale factor = new image/old image Pick a point, so P. P is the old image. P' is the new image. to determine the scale factor we can either use the corresponding x coordinate or ycoorindates. using the coordinates P'(1, −2) (new image) old image P(3, −6)) therefore using x coorindate scale factor = P'/P = 1/3 or using y coorindate scale factor = P'/P = 2/6=1/3 therefore scale factor = 1/3 we can see this seems right because the new image is smaller than the old image

Best ResponseYou've already chosen the best response.0Triangle P'Q'R' has vertices P'(1, −2), Q'(0, 3), and R'(−1, 0). Therefore, P"Q"R" have verticies P''(1,2) Q'' (0,3) R''(1,0)

Best ResponseYou've already chosen the best response.0B) since yreflection means each point (x, y) goes to (x, y) Therefore, Triangle P'Q'R' has vertices P'(1, −2), Q'(0, 3), and R'(−1, 0). Therefore, P"Q"R" have verticies P''(1,2) Q'' (0,3) R''(1,0)
