Triangles, Day 5, Week 7, SF

Triangles (2017)Piper AlldredgeComment

My friends, this week we definitely achieved triangularity. Triangles are such a fascinating shape for so many reasons.

With any three lengths or angles, you can only make one triangle. Similarly, since three points form a plane, a chair with three legs, no matter their lengths, will always stand stable on the floor (even if the floor isn't level).

These properties have fascinated mathematicians across the ages, and this week was no different. 

The bridge stood up! But, we heard some cracking on its way up, so no campers walked across it. These campers learned a few very important lessons about triangles. Like how the sides of a right triangle are shorter than the hypotenuse! This miscalculation meant that their beautiful trusses were too short to stand underneath the deck of the bridge and support it like they had designed.

Claire, Lucida and Mia demonstrate what it felt like to stand inside the icosahedron. 

Ethan and Mia demonstrates the pyramid (with triangular operating system?). Check out that mouse!

Okidoke, that's a wrap for this fantastic, three-sided week. Be sure to check out the flickr in order to see pictures from throughout the week!
