Why do engineers use triangles in bridges, towers, roofs, cranes—and even bicycle frames?
Because unlike a square frame, a triangle naturally holds its shape. When force is applied, a square can distort sideways. A triangle transfers that force through its three sides, helping the structure resist racking.
That simple geometry is one of the quiet reasons our built world can stand strong.
In this video, we break down why triangles appear everywhere in engineering—and why the shape matters far more than most people realise.
