Triangle pqr is transformed to triangle p′q′r′. triangle pqr has vertices p(4, −8), q(0, 12), and r(−4, 0). triangle p′q′r′ has vertices p′(1, −2), q′(0, 3), and r′(−1, 0).
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)
