**How to find the lines of symmetry?**

The lines of symmetry are imaginary lines that divide a shape or an object into two identical halves that are mirror images of each other.

Here are the general steps to find the lines of symmetry:

- Identify the shape or object you want to find the lines of symmetry for.
- Look for any obvious lines of symmetry. For example, a square has four lines of symmetry. In general, a regular polygon with n sides will have n lines of symmetry.
- If there are no obvious lines of symmetry, you can try folding the shape or object along different lines and see if the two halves match up perfectly. If they do, the line you folded along is a line of symmetry.
- You can also use a ruler or a piece of paper to help you find lines of symmetry. Place the ruler or paper along different parts of the shape or object and see if there is a line that divides it into two mirror images.
- Note that not all shapes or objects have lines of symmetry, and some may have multiple lines of symmetry.
