Triangles are stronger than squares because forces applied by a load are equally distributed. Triangles can be combined to make trusses that are used in a variety of structures like bridges, cranes and roofs. Toys such as Erector Sets, as well as housefold items such as straws, toothpicks and popsicle sticks can be used to experiment with different structures.
