On the sixth day of Christmas, my true love sent to me…

Six-fold symmetrical snowflakes

I hope you enjoy playing with my little snowflake-generator above – move the five points on the right to create snowflake designs on the left! Made of course with GeoGebra – if you haven’t already heard me wax lyrical about this fab bit of software, that means you didn’t read Monday’s blog post.

The snowflake generator was made in a slightly different way from the method I used in my GeoGebra workshop before Christmas – I created a polygon, reflected it in the y-axis, and then used the spreadsheet to quickly rotate each polygon through multiples of 60°. By changing this angle from 60° to 45° you could make designs with eight-fold symmetry (but don’t call them snowflakes or you’ll incur the wrath of the anti-snowfake campaigners!)

If you create any pleasing snowflake designs, do share a screengrab with me, and if you have other ideas for GeoGebra things you think I should create or you’d like me to run a GeoGebra workshop for you, get in touch!
