1. A figure is said to have line symmetry if a line can be drawn dividing the figure into two identical parts.
2. This line is called a
2. A figure may have no line of symmetry, only one line of symmetry, two lines of symmetry or
| Number of lines of symmetry | Example |
|---|---|
| No line of symmetry | A |
| Only one line of symmetry | An |
| Two lines of symmetry | A |
| Three lines of symmetry | An |
| Countless lines of symmetry | A |
3. The line symmetry is closely related to
4. When dealing with mirror reflection, we have to take into account the left ↔ right changes in orientation.
5. Symmetry has plenty of applications in everyday life as in art, architecture, textile technology, design creations, geometrical reasoning, Kolams, Rangoli etc.
