Is triangle DFE a reflection of triangle ABC over the y-axis? If not, what point(s) D, F, E would need to be corrected?

Question

A. Yes it is a reflection
B. No it is not a reflection, unless Point E is corrected
C. No it is not a reflection, unless Point F is corrected
D. No it is not a reflection, unless Point D is corrected
E. No it is not a reflection, unless points D & F are corrected

Answer 1

E. No it is not a reflection, unless points D & F are corrected

To be a reflection over the y-axis, the x-coordinate of each point in triangle DFE must be the negative of the x-coordinate of the corresponding point in triangle ABC. In this case, points D and F need to be corrected in order for triangle DFE to be a reflection of triangle ABC over the y-axis.
