Geodesic DomeGeodesic domes are incredible structuress that are almost spherical (shaped like a ball.) They are special buildings because they are quite energy efficient and relatively simple to build.

An architect named R. Buckminster Fuller, also known as “Bucky” Fuller, designed this building. He had many ideas on how to make buildings cheaper to build by using materials and building techniques in non-traditional ways.

This geodesic dome building was built in Montreal, Canada in 1967 and it was quite a strange sight!

What is the simplest geometric shape that is repeated in this building?
