Explaining The Universe on Instagram: "The triangle is considered the strongest geometric shape because of how it distributes force evenly across all three of its sides. When pressure is applied to one corner of a triangle, that force is spread out along the other two sides and shared by all three angles, preventing it from easily bending or collapsing. Unlike squares or rectangles, which can distort into a parallelogram when pushed, a triangle maintains its shape unless one of its sides breaks.
