Concept:A line of symmetry divides a figure into two identical halves that can be folded onto each other perfectly.Explanation:Observe the given figure carefully. There are multiple lines along which the figure can be folded so that the two halves coincide exactly. Count the lines: three lines pass through opposite vertices, and three lines pass through the midpoints of opposite sides. In total, there are 6 such lines. Each one is a line of symmetry. Therefore, the figure has 6 lines of symmetry.
