Overview of Some of the<br />
Mathematics Found in Snowflakes<br />
Symmetry<br />
• Rotational symmetry – snowflake rotated or turned &<br />
still looks same<br />
• Reflection or mirror symmetry – one half of snowflake<br />
image is reflection of other half<br />
• 6-fold symmetry (Stellar dendrite snowflake types) –<br />
hexagon looks same after being rotated 360° for 6<br />
turns about its axis<br />
• 3-fold symmetry (truncated triangular) - triangle looks<br />
same after being rotated 360° for 3 turns about its axis
