What is symmetry?
A shape has symmetry when you can fold it so that the two halves match exactly. The fold is called the line of symmetry. A mirror placed on that line shows the whole shape.
Even a train 🚂 engine seen from the front is symmetrical, with one light on each side!
Shapes to know
| Shape | Lines of symmetry | Fold |
|---|---|---|
| 🟦 square | 4 | middle and diagonals |
| 📄 rectangle | 2 | middle only |
| 🔺 equilateral triangle | 3 | corner to side |
| ⭕ circle | countless | any line through the centre |
How to check for symmetry
- Imagine a fold down the middle.
- Then try a fold across the middle.
- Then try the diagonals.
- Count every fold where the halves match.

Solved examples
Common mistakes
| Mistake | Correct |
|---|---|
| A rectangle has 4 lines of symmetry | It has 2. The diagonals do not work. |
| Every letter is symmetrical | Letters like F, G, J and R have none. |
| 2 and 5 look the same in a mirror | Only 0, 1 and 8 do. |
| Circles tile a floor | Circles leave gaps. Squares and hexagons do not. |
Daily life
We see symmetry in butterflies, leaves, flowers, rangoli, kites, buildings and floor tiles. Mirror writing on ambulances helps drivers make way quickly.
Tips for parents and teachers
- Make ink blot designs by folding paper.
- Use a small mirror to test letters and numbers.
- Fold and cut paper to make snowflakes and count the holes.
- Collect leaves and sort them into symmetrical and not symmetrical.
- Let the child retry the challenges to earn 3 stars.
