Lines of Symmetry

In order to follow the mathematical theory of posing (as postulated by me!), the reader first needs to understand what is meant by a line of symmetry.

Here is a simple square: which I add a simple dashed line: The dashed line is a line of symmetry, which is defined as: the part of the shape either side of the line could be reflected to create the entire shape.


Here are some more squares with lines of symmetry: An equilateral triangle has three lines of symmetry, an isosceles triangle only one. Hopefully these simple diagrams will illustrate this clearly to the reader:

Other shapes have possible lines of symmetry; in fact the circle has infinite numbers of lines of symmetry provided the line goes through the centre of the circle, ie is a line of diameter.
