The geodesic dome was invented in the late 1940's
The 'big ball' at Epcot in Orlando Florida, is a Geodesic sphere. The old dome-like playground equipment is based on the same structure as a geodesic dome. I've posted a couple of links about geodesic domes with some pictures.

The largest geodesic dome is the Fantasy Entertainment Complex and is located in Kyosho Isle, Japan. It stands at 710 feet.

A geodesic dome is made up of many triangles and very strong.
Equilateral and isoceles triangles
The basic concept of a geodesic dome is very simple. It is composed of a series of triangles, and the triangle is a rigid shape. That's why the dome stays up.
A geodesic dome is a shell that is made of a lot of small triangles (typically) and is shaped like a sphere. (for more information on this, please go to the wikipedia article, thanks.)
The answer varies depending on the exact type of geodesic dome you are using. A 2 frequency and 4 frequency geodesic domes use 20 equilateral triangles despite the two-frequency having many more faces than the 2 frequency where the 3 frequency geodesic dome (150 sided) uses none at all. The above calculations, however, are only common to a certain architectural model. Assuming the domes are built mathematically instead of according to architectural integrity, the number of equilateral triangles in a "pure" dome, a geodesic sphere, is exactly equal to the number of faces, by definition.
Geodesic domes are used by individuals, communities, and organizations for various purposes such as greenhouses, event spaces, disaster relief shelters, and even homes. They are valued for their strength, energy efficiency, and unique design.

yes. every square or rectangle and be divided into two triangles by connecting a pair of opposite corners.
