the triangle pqr is transformed to the triangle p'q'r. Triangle PQR has verticals P(3,1) Q(1,2) R(2,5). Triangle P'Q'R' has verticals P'(6,2) Q'(2,4) and R'(4,10) 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 P'Q'R'? Explain Part B: Write the coordinates of tria reflected about the y-axis Part C: Are the two triangles PQR and P"Q"R" congruent? Explain
