Triangle end is reflected across the line y = x using the rule (x, y) → (y, x) to create triangle e′n′d′. if a line segment is drawn from point e to point e′, which statement would best describe the line segment drawn in relation to the line y = x?
both are congruent to each other.
both create diameters of concentric circles.
they are parallel.
they are perpendicular.
