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)
