Building with Triangles

Engineers and architects use trigonometry to design everything from bridges to roller coasters. Triangles give structures strength and stability.

Where Trig Shows Up

  • Calculating forces in bridge supports.
  • Designing sloped roofs and ramps.
  • Laying out curved paths and arches.

Trigonometry makes sure buildings are safe and look amazing!

Examples

  • An architect calculates the length of a roof beam using the angle of the roof.

  • A roller coaster’s loop is designed using the properties of a circle and trigonometric functions.
