Symmetry is all around us in nature, art, and design. This
presentation will explore what symmetry is and how it plays a
role in the world.
Symmetry :
Symmetry is when a shape can be divided into two identical
halves that overlap each other perfectly.

Origin of the Word 'Symmetry' :
The word 'symmetry' comes from the Greek word symmetros,
meaning "even."
Shapes and Symmetry :
A shape is symmetric if you can draw an imaginary line through
it and the two halves match perfectly when folded.
