The question means: How many lines can you draw through the center of this figure, so that if you fold the figure in half along the line, both sides will be perfectly superimposed?

OpenStudy (mathstudent55):

Here is an example wit a square. |dw:1438286601391:dw| If you fold the square along that line, you get the two halves exactly on top of each other. That means that is 1 line of symmetry.

Here is another line of symmetry. |dw:1438286661309:dw|

OpenStudy (mathstudent55):

Here are the other 2 lines of symmetry. |dw:1438286697858:dw|

OpenStudy (mathstudent55):

A square 4 lines of symmetry.

With a regular hexagon, you have: |dw:1438286789906:dw| There are 6 different lines of symmetry.
