Final answer:
We can conclude that E is the midpoint of HJ and EF is perpendicular to HJ if EF is the perpendicular bisector of HJ. Without further information, no additional conclusions can be drawn.
Step-by-step explanation:
In the context of the question provided, we cannot conclude anything that is not a direct consequence of the given information. Specifically, because EF is the perpendicular bisector of HJ, we know that E is the midpoint of HJ and that EF is perpendicular to HJ. However, without additional information or given angle measures or side lengths, we cannot conclude any congruencies or specific angle sizes beyond what the definition of a perpendicular bisector entails. As for the other provided statements, they seem to be unconnected to the core question about the perpendicular bisector, and hence, do not provide a basis for additional conclusions related to the original geometry problem.
