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)

    start by using the "draw" to sketch the figures

    the dilation factor is the ratio of the corresponding lengths this means you have to find the length for example of PQ and P'Q' then set as ratio

    to reflect about the y-axis the x coordinate will become -x and the y coordinate will stay the same

    |dw:1440022908017:dw| the blue dot is the point (2, 4) when reflected across the y-axis it will now be at the green spot. it moves the same distance in the opposite direction from the "mirror" y-axis. and at the same height/y value 4 it is now at (-2, 4)

    you need to label the points, axis and on the same grid put P'Q'R'
