什么形状是最稳固的?
Why?
1. Because the triangle does not easily deform and is able to balance the stretching and compressive forces inside the structure.2. For economic reasons: since the triangle obviously has only 3 sides, it requires little material to make a support, thus minimizing the costs.Overall, a triangle is the simplest geometric figure that will not change shape when the lengths of the sides are fixed.
