Exploring Strong Structures with Triangles

What is the primary reason triangles are used in structures?

• To provide support, stability, and stiffness

• To increase the height of structures

• To reduce material cost

• For aesthetic appeal

What materials were used to demonstrate the structural project?

• Wood sticks and candies

• Plastic tubes and jelly beans

• Toothpicks and gummy worms

• Metal rods and marshmallows

Why did the structure built with parallelograms fail?

• The gummy connectors melted

• The structure flattened under weight

• The colors were not bright enough

• The toothpicks were too short

What is the name of the triangular 3D structure mentioned?

• Tetrahedron

• Cube

• Cylinder

• Hexagon
