Who says geometry isn't everywhere??

In geometry, my students are currently working on a project where they get to pick a theme of their choice and find a series of 18 different geometric concepts encorporated into that theme. Well as I was strolling memory lane, I was looking at my wedding pics and came across this gem! How many geometric concepts can you find here?

I see.... Parallel lines cut by a transversal (in the lattice work in the frosting) and I also see 3 similar hexagons (congruent angles, different side lengths). Maybe later on in the semester we'll find its surface area and volume! Yum
