Detailed theory
Fold along a line — if halves coincide, shape has line symmetry. A, M, T are symmetric; F, G, J are not.
Key concepts & formulas
01
**Line symmetry**: shape maps onto itself when folded.
02
The fold line is the **axis of symmetry**.
03
Shapes may have axes; a circle has infinite.
04
**Rotational symmetry**: shape looks same after a partial turn.
05
**Order**: number of matches in one full turn.
