Chapter Overview
A line of symmetry divides a figure into two mirror-image halves.
Does it Look the Same? explores line symmetry and rotational symmetry. Learners test folds, complete mirror halves, and identify shapes that match themselves after a turn.
Line Symmetry
- Matching halves overlap exactly when folded along a symmetry line.
- A figure may have no line, one line, or several lines of symmetry.
- A square has four lines of symmetry; a non-square rectangle has two.
- Details and orientation must mirror across the line.
Rotational Symmetry
- A figure has rotational symmetry if it matches before a full turn.
- Order of rotational symmetry counts matches in one full turn.
- A square matches four times in 360°.
- A shape can have line symmetry, rotational symmetry, both, or neither.

Find Symmetry Order
How many times does a square match its starting appearance during one full turn?
- 1It matches after 90°, 180°, 270°, and 360°.
- 2Count these matching positions.
- 3There are four matches.
Answer
Order 4
Key Points to Remember
- ✓ Mirror halves define line symmetry
- ✓ Folding can test a symmetry line
- ✓ Rotational symmetry involves turning
- ✓ Symmetry order counts matches in 360°
Exam Tips
- • Include colours and markings when checking symmetry
- • Trace or fold mentally across the proposed line
- • Do not count the starting position twice
