A line of symmetry is an imaginary line that divides a shape or object into two equal and mirror-image halves.
When a shape has a line of symmetry, it means that one half can be reflected or flipped over the line to match and overlap perfectly with the other half.
Line symmetry is a fundamental concept in geometry and is commonly found in various geometric shapes, such as circles, rectangles, and equilateral triangles.
It is used in design, art, and mathematics to create visually balanced and aesthetically pleasing compositions.
