Final Answer:
The correct reflections and mirror lines are drawn as follows:
1) The triangle is flipped upside down across the horizontal mirror line.
2) The quadrilateral is flipped upside down across the horizontal mirror line.
3) The pentagon is flipped upside down across the horizontal mirror line.
4) The shape is flipped left-right across the vertical mirror line.
5) The hexagon is flipped left-right across the vertical mirror line.
6) The parallelogram is flipped diagonally across the diagonal mirror line (top-left to bottom-right).
7) The U-shape is flipped diagonally across the diagonal mirror line (top-left to bottom-right).
8) The triangle is flipped diagonally across the diagonal mirror line (top-left to bottom-right).
Section B: The mirror line is drawn vertically down the middle of the combined shape, separating the blue and yellow parts symmetrically.
