Snow Flakes are almost always variations on which geometric shape?
According to Wikipedia: Large, well formed snowflakes are relatively flat and have six approximately identical arms, so that the snowflake nearly has the same 6-fold dihedral symmetry as a hexagon or hexagram. This symmetry arises from the hexagonal crystal structure of ordinary ice. However, the exact shape of the snowflake is determined by the temperature and humidity at which it forms.[1]. Rarely, at a temperature of around -2 °C (28 °F), snowflakes can form in threefold symmetry – triangular snowflakes. [2] Snowflakes are not perfectly symmetric however. The most common snowflakes are visibly irregular, although near-perfect snowflakes may be more common in pictures because they are more visually appealing.
