Triangles are the strongest basic shape for building structures because the center of gravity is lower, the angles cannot change, and load is transferred smoothly. Common structures like bridges and buildings are built using triangular components like diagonal braces and trusses to reinforce them against forces and make them more stable. Examples provided include the great pyramids, bridges, and buildings that demonstrate real-world applications of triangular reinforcement in construction.

7. CircleWHY TRIANGLE IS STRONGEST SHAPE? The centre of gravity is 1/3 of its height Cg

8. WHY TRIANGLE IS STRONGEST SHAPE? The angle cannot change once the triangle is buildExample of angle adjustable for square

9. WHY TRIANGLE IS STRONGEST SHAPE? the load from structure will transfer smoothly Strengthening Squares Add a diagonal between opposite corners Example in our real life
