Which single transformation or sequence of transformations would take triangle ABC to the image A'B'C'? Check all that apply. 2 triangles in a coordinate plane. One triangle has vertices A negative 5, 5; B negative 1, 1; and C negative 5, 1. The other triangle has vertices A prime 2 point 5, negative 1 point 5; B prime 0 point 5, negative 3 point 5; and C prime 2 point 5, negative 3 point 5. (A) Dilation by a scale factor of 1/2 , rotation of 180° about the origin, and a translation up 1. (B) Reflection across y-axis, translation up 2 units, dilation by a scale factor of 1/2 , and a translation down 5 units. (C) Dilation by a scale factor of 2, reflection across the y-axis, and a translation down 4 units. (D) Dilation by a scale factor of 1/2 , reflection across the y-axis, and a translation down 4 units. (E) Dilation by a scale factor of 2, translation down 4 units, and reflection across the y-axis. (F) Translation down 6 units, reflection across y-axis, dilation by a scale factor of 1/2 , and a translation down 1 unit.
