1. The problem involves completing figures by reflecting points across given lines of symmetry. 2. For each figure, identify a point not on the line of symmetry and count the number of spaces from the line to that point. 3. Reflect the point across the line by counting the same number of spaces on the opposite side. 4. Connect the reflected points with line segments to complete the figure. 5. For figures 8 and 9, the lines of symmetry are horizontal and diagonal respectively; for figures 10 and 11, multiple lines of symmetry are drawn. 6. The process uses the rule that points and their reflections are equidistant from the line of symmetry. 7. By repeating this reflection and connection process, the figures become symmetric about the given lines. Final answer: The figures are completed by reflecting points across the lines of symmetry and connecting them, ensuring the figures are symmetric as described.
