Why are triangles such a strong shape to build with?
In: Engineering
If you push down at the top of a triangle, the edges cannot be pushed to the side. Because they’re at acute angles (less than 90 degrees), the edge would have to swing upward before it could swing outward.
If you push down on top of a square, the edges can just collapse to the side. Add even more sides and it can just collapse into itself.
