Chapter 12 – Symmetry

Important Concepts

• Symmetry is a geometrical concept that is found in most cases including nature.
• Any geometric shape can be said to be symmetric or asymmetric
• A shape is said to be symmetric if there exists an imaginary line passing through that divides the shape into halves and that these halves overlap each other completely.
• In other words, fold the shape about the imaginary line to check if the two halves completely overlap each other or not. If they overlap each other completely the shape is symmetric, if not, then it is asymmetric.
• The imaginary line is called as the line of symmetry.
• The symmetry observed in the above example is called as a line symmetry or bilateral symmetry.

Lines of Symmetry for Regular Polygons

• Regular polygons are closed shapes that have equal sides and equal angles.
• Such polygons have multiple lines of symmetry.

Some regular polygons with their line of symmetry are shown below:

Rotational Symmetry

• There exists another concept of symmetry that does not involve folding the figure to check if they coincide.
• Rotational symmetry is one where when a figure is rotated about a centre point, the figure looks exactly the same before rotation.
• The particular centre for which rotational symmetry is observed is called the centre of rotation.
• The angle of turning during rotation is called angle of rotation.
• The number of positions in which a figure can be rotated and still appears exactly like it did before the rotation is called order of symmetry.
