Sounds like a nice idea if we had great weather 365.
I was actually asked this question during an interview a few years ago. At first, I wasn’t sure where to go with it. What did he mean ‘schools without walls’? What’s holding up the roof? What was he really asking me?
A triangle is the ONLY two dimensional polygon that cannot collapse or bend — it is surprisingly strong for its simple shape. That’s its beauty — all 3 sides work together to find strength. A square – -a shape with just one more side — doesn’t have this strength. It will easily bend or collapse.
A Triangle Easily Resists an Applied Force, but a Square Folds Like a Cheap Tent
The triangle is well known to engineers who use it ubiquitously in our world because of its elegance and surprising strength. You can’t walk down the street without seeing triangles just about everywhere.
