3-Sided Triangular Snowflakes

3-Sided, triangular shaped snow crystals can appear with the same weather conditions that produce 6 sided, hexagonal shaped snowflakes. The most common snow crystal shape is the 6 sided hexagon. The hexagon is a polygon with six edges and six vertices. The hexagon is a primary natural shape that can be seen in honey combs of bees. Just as with squares and equilateral triangles, regular hexagons can fit tightly together without showing any gaps. Snowflake patterns are paper cut-out shapes which are not only fun to make but useful to help introduce math concepts to children.
