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?

  1. 1It matches after 90°, 180°, 270°, and 360°.
  2. 2Count these matching positions.
  3. 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
