Going Beyond

 

Geodesic domes are elegant and sophisticated structures. They are lightweight, extremely strong, and earthquake proof, and these domes make an efficient use of materials. Domes are ideal structures to create unobstructed internal space or for their use in challenging building sites, like the Arctic. If you look carefully at the photographs, you will likely notice triangles are once again a major component of the design.

 

Two photos show geodesic domes.

The construction of these domes uses spherical trigonometry to figure out the angles at which triangles are joined to create the three-dimensional spherical structure in a geodesic dome. You may want to further investigate spherical trigonometry and this unique type of construction.
