This is a square prism. The bases of this type of prism are squares. In square prisms the opposite sides and angles are congruent. In this problem, we need to find which line segment is parallel to GE, so the right answer is KI as solved in the Figure bellow. Recall that parallel lines are lines that have the same distance apart called equidistant.
In your question where as the figure show the rectangular prism and ask on which of the following in your choices is parallel to GE and the answer is KI. I hope you are satistfied with my answer and if you need some clarification, please feel free to ask for more
