Line symmetry exists when one half of a shape is the mirror image of the other half. Many common shapes and structures exhibit line symmetry, including letters of the alphabet, road signs, polygons, and architectural landmarks like the Taj Mahal. The document explores line symmetry through examples, activities identifying symmetrical shapes, and explanations of what qualifies as a line of symmetry.

2. Line Symmetry Shape has line symmetry when one half of it is the mirror image of the other half. Symmetry exists all around us and many people see it as being a thing of beauty.

3. Is a butterfly symmetrical?

4. The Taj Mahal Symmetry exists in architecture all around the world. The best known example of this is the Taj Mahal.

5. Let’s talk about Lines of Symmetry If a shape can be folded in half so that one half fits exactly on top of the other, then we say that the shape has got line symmetry . The fold is called a line of symmetry. This shape has got a vertical line of symmetry.
