Solution
When the shaded figure in
[[IMAGE0]]
is reflected about the line segment , the resulting figure is
[[IMAGE1]]
This is because the figure started above the line and so finished below the line, and the figure initially touched the line at two points, so finishes still touching the line at two points.
