triangle pqr is transformed to triangle p'q'r'. triangle pqr has vertices p(8, 0), q(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 p''q''r'' congruent? explain your answer. (2 points)
