WebLines of Symmetry: We see symmetry when we have an exact copy or replica of a shape. In geometry, when you draw a line of symmetry, the shape or object is exactly the same on both sides of the line. Imagine a simple example: if you folded a square exactly in half so that each side is the same, the fold is the line of symmetry.
