(02.05 MC) Triangle PQR is transformed to triangle P'Q'R'. Triangle PQR has vertices P(8, 0), Q(6, 2), and R(β2, β4). Triangle P'Q'R' has vertices P'(4, 0), Q'(3, 1), and R'(β1, β2). 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)

Given: ae β
ce ; de β
be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that β³aeb β
β³ced, we can show that β³ β
β³ceb by. so, β cad β
β by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
