How would you define the term 'line symmetry'? Why might some people see line symmetry as a thing of beauty?
This type of symmetry is also called reflectional symmetry as the two parts reflect/match along each side of a dividing line ( or axis ).
There are also many examples of symmetry inside the human body e.g. the lungs, the kidneys, the brain, the skull, etc.
In this view of the building there is a line of symmetry through the centre of the tomb from top to bottom. It was completed in 1630 by the Indian ruler Shahs Jahan as a tomb for his favourite wife Mumtaz Mahal who died as a result of giving birth to their 14th child. To build this tomb it took 20 000 workers, 20 years (Encarta 97) and it is rumoured that they used 40 000 elephants to transport the materials.
Is there a pattern here? How could you prove that a square really does have 4 lines of symmetry and not 2. A rectangle has 4 lines of symmetry. True or False? How could you prove it? What pattern can you see emerging on this page?
