Triangle pqr has vertices p(3, - 6) ), q(0, 9) , and f(- 3, 0) . triangle p'o'r has vertices p^ prime (t,-2) , q^ prime (0,3) , and thange por is transformed to triangle po'r r^ prime /-1,0) plot triangles por and p^ prime q^ prime r^ prime on your own coordinate and part a what is the scale factor of the dilation that transforms triangle por to triangle p'o'r'! explain your answer. (4 points) part b: write the coordinates of triangle p q r obtained after p^ prime q^ prime r^ prime ' is reflected about the y-axis. 4 points) part 6: are the two triangles por and p^ prime prime q^ prime prime r^ prime prime congruent? explain your answer (2 points)
